refactor a dup logic

Simplifies repeated postFormData + mountExploreUrl + dashboard_page_id pattern
used across 6+ files by providing a clean, type-safe async utility.

Benefits:
- DrillDetailModal: 15 lines → 5 lines (67% reduction)
- Centralized URL generation logic for better maintainability
- Type-safe options parameter for chartId, tabId, dashboardPageId
- Comprehensive test coverage with 4 test scenarios
- Better error handling and promise chain management

Files refactored:
- DrillDetailModal: Simplified async URL generation
- DrillByModal: Clean promise chain with proper error handling
- SqlLab ResultSet: Modern async/await pattern
- Added comprehensive utility tests

All component tests passing ✅

+## Pull Request Guidelines
+
+**When creating pull requests:**
+
+1. **Read the current PR template**: Always check `.github/PULL_REQUEST_TEMPLATE.md` for the latest format
+2. **Use the template sections**: Include all sections from the template (SUMMARY, BEFORE/AFTER, TESTING INSTRUCTIONS, ADDITIONAL INFORMATION)
+3. **Follow PR title conventions**: Use [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/)
+   - Format: `type(scope): description`
+   - Example: `fix(dashboard): load charts correctly`
+   - Types: `fix`, `feat`, `docs`, `style`, `refactor`, `perf`, `test`, `chore`
+
+**Important**: Always reference the actual template file at `.github/PULL_REQUEST_TEMPLATE.md` instead of using cached content, as the template may be updated over time.
+
 ## Pre-commit Validation

+## ECharts Configuration Overrides
+
+:::note
+Available since Superset 6.0
+:::
+
+Superset provides fine-grained control over ECharts visualizations through theme-level configuration overrides. This allows you to customize the appearance and behavior of all ECharts-based charts without modifying individual chart configurations.
+
+### Global ECharts Overrides
+
+Apply settings to all ECharts visualizations using `echartsOptionsOverrides`:
+
+```python
+THEME_DEFAULT = {
+    "token": {
+        "colorPrimary": "#2893B3",
+        # ... other Ant Design tokens
+    },
+    "echartsOptionsOverrides": {
+        "grid": {
+            "left": "10%",
+            "right": "10%",
+            "top": "15%",
+            "bottom": "15%"
+        },
+        "tooltip": {
+            "backgroundColor": "rgba(0, 0, 0, 0.8)",
+            "borderColor": "#ccc",
+            "textStyle": {
+                "color": "#fff"
+            }
+        },
+        "legend": {
+            "textStyle": {
+                "fontSize": 14,
+                "fontWeight": "bold"
+            }
+        }
+    }
+}
+```
+
+### Chart-Specific Overrides
+
+Target specific chart types using `echartsOptionsOverridesByChartType`:
+
+```python
+THEME_DEFAULT = {
+    "token": {
+        "colorPrimary": "#2893B3",
+        # ... other tokens
+    },
+    "echartsOptionsOverridesByChartType": {
+        "echarts_pie": {
+            "legend": {
+                "orient": "vertical",
+                "right": 10,
+                "top": "center"
+            }
+        },
+        "echarts_timeseries": {
+            "xAxis": {
+                "axisLabel": {
+                    "rotate": 45,
+                    "fontSize": 12
+                }
+            },
+            "dataZoom": [{
+                "type": "slider",
+                "show": True,
+                "start": 0,
+                "end": 100
+            }]
+        },
+        "echarts_bubble": {
+            "grid": {
+                "left": "15%",
+                "bottom": "20%"
+            }
+        }
+    }
+}
+```
+
+### UI Configuration
+
+You can also configure ECharts overrides through the theme CRUD interface:
+
+```json
+{
+  "token": {
+    "colorPrimary": "#2893B3"
+  },
+  "echartsOptionsOverrides": {
+    "grid": {
+      "left": "10%",
+      "right": "10%"
+    },
+    "tooltip": {
+      "backgroundColor": "rgba(0, 0, 0, 0.8)"
+    }
+  },
+  "echartsOptionsOverridesByChartType": {
+    "echarts_pie": {
+      "legend": {
+        "orient": "vertical",
+        "right": 10
+      }
+    }
+  }
+}
+```
+
+### Override Precedence
+
+The system applies overrides in the following order (last wins):
+
+1. **Base ECharts theme** - Default Superset styling
+2. **Plugin options** - Chart-specific configurations
+3. **Global overrides** - `echartsOptionsOverrides`
+4. **Chart-specific overrides** - `echartsOptionsOverridesByChartType[chartType]`
+
+This ensures chart-specific overrides take precedence over global ones.
+
+### Common Chart Types
+
+Available chart types for `echartsOptionsOverridesByChartType`:
+
+- `echarts_timeseries` - Time series/line charts
+- `echarts_pie` - Pie and donut charts
+- `echarts_bubble` - Bubble/scatter charts
+- `echarts_funnel` - Funnel charts
+- `echarts_gauge` - Gauge charts
+- `echarts_radar` - Radar charts
+- `echarts_boxplot` - Box plot charts
+- `echarts_treemap` - Treemap charts
+- `echarts_sunburst` - Sunburst charts
+- `echarts_graph` - Network/graph charts
+- `echarts_sankey` - Sankey diagrams
+- `echarts_heatmap` - Heatmaps
+- `echarts_mixed_timeseries` - Mixed time series
+
+### Best Practices
+
+1. **Start with global overrides** for consistent styling across all charts
+2. **Use chart-specific overrides** for unique requirements per visualization type
+3. **Test thoroughly** as overrides use deep merge - nested objects are combined, but arrays are completely replaced
+4. **Document your overrides** to help team members understand custom styling
+5. **Consider performance** - complex overrides may impact chart rendering speed
+
+### Example: Corporate Branding
+
+```python
+# Complete corporate theme with ECharts customization
+THEME_DEFAULT = {
+    "token": {
+        "colorPrimary": "#1B4D3E",
+        "fontFamily": "Corporate Sans, Arial, sans-serif"
+    },
+    "echartsOptionsOverrides": {
+        "grid": {
+            "left": "8%",
+            "right": "8%",
+            "top": "12%",
+            "bottom": "12%"
+        },
+        "textStyle": {
+            "fontFamily": "Corporate Sans, Arial, sans-serif"
+        },
+        "title": {
+            "textStyle": {
+                "color": "#1B4D3E",
+                "fontSize": 18,
+                "fontWeight": "bold"
+            }
+        }
+    },
+    "echartsOptionsOverridesByChartType": {
+        "echarts_timeseries": {
+            "xAxis": {
+                "axisLabel": {
+                    "color": "#666",
+                    "fontSize": 11
+                }
+            }
+        },
+        "echarts_pie": {
+            "legend": {
+                "textStyle": {
+                    "fontSize": 12
+                },
+                "itemGap": 20
+            }
+        }
+    }
+}
+```
+
+This feature provides powerful theming capabilities while maintaining the flexibility of ECharts' extensive configuration options.

-For E2E testing, we recommend that you use a `docker compose` backend
+**Note: We are migrating from Cypress to Playwright. Use Playwright for new tests.**
+
+#### Playwright (Recommended - NEW)
+
+For E2E testing with Playwright, use the same `docker compose` backend:
 
 ```bash
 CYPRESS_CONFIG=true docker compose up --build
 ```
-`docker compose` will get to work and expose a Cypress-ready Superset app.
-This app uses a different database schema (`superset_cypress`) to keep it isolated from
-your other dev environment(s), a specific set of examples, and a set of configurations that
-aligns with the expectations within the end-to-end tests.  Also note that it's served on a
-different port than the default port for the backend (`8088`).
 
-Now in another terminal, let's get ready to execute some Cypress commands. First, tell cypress
-to connect to the Cypress-ready Superset backend.
+The backend setup is identical - this exposes a test-ready Superset app on port 8081 with isolated database schema (`superset_cypress`), test data, and configurations.
 
+Now in another terminal, run Playwright tests:
+
+```bash
+# Navigate to frontend directory (Playwright config is here)
+cd superset-frontend
+
+# Run all Playwright tests
+npm run playwright:test
+# or: npx playwright test
+
+# Run with interactive UI for debugging
+npm run playwright:ui
+# or: npx playwright test --ui
+
+# Run in headed mode (see browser)
+npm run playwright:headed
+# or: npx playwright test --headed
+
+# Run specific test file
+npx playwright test tests/auth/login.spec.ts
+
+# Run with debug mode (step through tests)
+npm run playwright:debug tests/auth/login.spec.ts
+# or: npx playwright test --debug tests/auth/login.spec.ts
+
+# Generate test report
+npx playwright show-report
 ```
+
+Configuration is in `superset-frontend/playwright.config.ts`. Base URL is automatically set to `http://localhost:8088` but will use `PLAYWRIGHT_BASE_URL` if provided.
+
+#### Cypress (DEPRECATED - will be removed in Phase 5)
+
+:::warning
+Cypress is being phased out in favor of Playwright. Use Playwright for all new tests.
+:::
+
+```bash
+# Set base URL for Cypress
 CYPRESS_BASE_URL=http://localhost:8081
 ```

+# Playwright E2E Tests for Superset
+
+This directory contains Playwright end-to-end tests for Apache Superset, designed as a replacement for the existing Cypress tests during the migration to Playwright.
+
+## Architecture
+
+```

+├── components/core/     # Reusable UI components
+├── pages/              # Page Object Models  
+├── tests/              # Test files organized by feature
+├── utils/              # Shared constants and utilities
+└── README.md           # This file
+```
+
+## Design Principles
+
+We follow **YAGNI** (You Aren't Gonna Need It), **DRY** (Don't Repeat Yourself), and **KISS** (Keep It Simple, Stupid) principles:
+
+- Build only what's needed now
+- Reuse existing patterns and components
+- Keep solutions simple and maintainable
+
+## Component Architecture
+
+### Core Components (`components/core/`)
+
+Reusable UI interaction classes for common elements:
+
+- **Form**: Container with properly scoped child element access
+- **Input**: Supports `fill()`, `type()`, and `pressSequentially()` methods
+- **Button**: Standard click, hover, focus interactions
+
+**Usage Example:**
+```typescript
+import { Form } from '../components/core';
+
+const loginForm = new Form(page, '[data-test="login-form"]');
+const usernameInput = loginForm.getInput('[data-test="username-input"]');
+await usernameInput.fill('admin');
+```
+
+### Page Objects (`pages/`)
+
+Each page object encapsulates:
+- **Actions**: What you can do on the page
+- **Queries**: Information you can get from the page  
+- **Selectors**: Centralized in private static SELECTORS constant
+- **NO Assertions**: Keep assertions in test files
+
+**Page Object Pattern:**
+```typescript
+export class AuthPage {
+  // Selectors centralized in the page object
+  private static readonly SELECTORS = {
+    LOGIN_FORM: '[data-test="login-form"]',
+    USERNAME_INPUT: '[data-test="username-input"]',
+  } as const;
+
+  // Actions - what you can do
+  async loginWithCredentials(username: string, password: string) { }
+
+  // Queries - information you can get  
+  async getCurrentUrl(): Promise<string> { }
+
+  // NO assertions - those belong in tests
+}
+```
+
+### Tests (`tests/`)
+
+Organized by feature/area (auth, dashboard, charts, etc.):
+- Use page objects for actions
+- Keep assertions in test files  
+- Import shared constants from `utils/`
+
+**Test Pattern:**
+```typescript
+import { test, expect } from '@playwright/test';
+import { AuthPage } from '../../pages/AuthPage';
+import { LOGIN } from '../../utils/urls';
+
+test('should login with correct credentials', async ({ page }) => {
+  const authPage = new AuthPage(page);
+  await authPage.goto();
+  await authPage.loginWithCredentials('admin', 'general');
+
+  // Assertions belong in tests, not page objects
+  expect(await authPage.getCurrentUrl()).not.toContain(LOGIN);
+});
+```
+
+### Utilities (`utils/`)
+
+Shared constants and utilities:
+- **urls.ts**: URL paths and request patterns
+- Keep flat exports (no premature namespacing)
+
+## Contributing Guidelines
+
+### Adding New Tests
+
+1. **Check existing components** before creating new ones
+2. **Use page objects** for page interactions  
+3. **Keep assertions in tests**, not page objects
+4. **Follow naming conventions**: `feature.spec.ts`
+
+### Adding New Components
+
+1. **Follow YAGNI**: Only build what's immediately needed
+2. **Use Locator-based scoping** for proper element isolation
+3. **Support both string selectors and Locator objects** via constructor overloads
+4. **Add to `components/core/index.ts`** for easy importing
+
+### Adding New Page Objects
+
+1. **Centralize selectors** in private static SELECTORS constant
+2. **Import shared constants** from `utils/urls.ts`
+3. **Actions and queries only** - no assertions
+4. **Use existing components** for DOM interactions
+
+## Running Tests
+
+```bash
+# Run all tests
+npm run playwright:test
+# or: npx playwright test
+
+# Run specific test file
+npx playwright test tests/auth/login.spec.ts
+
+# Run with UI mode for debugging
+npm run playwright:ui
+# or: npx playwright test --ui
+
+# Run in headed mode (see browser)
+npm run playwright:headed
+# or: npx playwright test --headed
+
+# Debug specific test file
+npm run playwright:debug tests/auth/login.spec.ts
+# or: npx playwright test --debug tests/auth/login.spec.ts
+```
+
+## Test Reports
+
+Playwright generates multiple reports for better visibility:
+
+```bash
+# View interactive HTML report (opens automatically on failure)
+npm run playwright:report
+# or: npx playwright show-report
+
+# View test trace for debugging failures
+npx playwright show-trace test-results/[test-name]/trace.zip
+```
+
+### Report Types
+
+- **List Reporter**: Shows progress and summary table in terminal
+- **HTML Report**: Interactive web interface with screenshots, videos, and traces
+- **JSON Report**: Machine-readable format in `test-results/results.json`
+- **GitHub Actions**: Annotations in CI for failed tests
+
+### Debugging Failed Tests
+
+When tests fail, Playwright automatically captures:
+- **Screenshots** at the point of failure
+- **Videos** of the entire test run
+- **Traces** with timeline and network activity
+- **Error context** with detailed debugging information
+
+All debugging artifacts are available in the HTML report for easy analysis.
+
+## Configuration
+
+- **Config**: `playwright.config.ts` - matches Cypress settings
+- **Base URL**: `http://localhost:8088` (assumes Superset running)
+- **Browsers**: Chrome only for Phase 1 (YAGNI)
+- **Retries**: 2 in CI, 0 locally (matches Cypress)
+
+## Migration from Cypress
+
+When porting Cypress tests:
+
+1. **Port the logic**, not the implementation
+2. **Use page objects** instead of inline selectors
+3. **Replace `cy.intercept/cy.wait`** with `page.waitForRequest()`
+4. **Use shared constants** from `utils/urls.ts`
+5. **Follow the established patterns** shown in `tests/auth/login.spec.ts`
+
+## Best Practices
+
+- **Centralize selectors** in page objects
+- **Centralize URLs** in `utils/urls.ts`  
+- **Use meaningful test descriptions**
+- **Keep page objects action-focused**
+- **Put assertions in tests, not page objects**
+- **Follow the existing patterns** for consistency
