fix(playwright): address review feedback on de-flake change

Three follow-ups from /review-code on the list-spec de-flake work:

- Revert toast assertions to expect(toast.getSuccess()).toBeVisible().
  The previous switch to toast.getSuccess().waitFor({ state: 'visible' })
  was a no-op: both APIs poll for visibility, so neither catches a fast
  auto-dismiss between polls. The expect() form fails as an assertion
  (clearer diff, counted in reports). Misleading "use waitFor so we
  detect auto-dismiss" comments are gone too.

- Drop redundant waitFor({ state: 'visible' }) calls in BulkSelect's
  selectRow / deselectRow / clickAction. Locator.check()/click() already
  auto-wait for visibility, stability, and enabled state. The
  expect(checkbox).toBeChecked() assertion -- which is the actual race
  guard against React state propagation -- stays.

- Expand the DeleteConfirmationModal.clickDelete docstring to explain
  why it bypasses Modal.clickFooterButton: the footer button label is
  i18n'd, so name-based lookups break in non-English locales.

+### Webhook integration
+
+Superset can send alert and report notifications to any HTTP endpoint — useful for chat platforms, incident management tools, or custom automation.
+
+#### Enabling Webhooks
+
+Enable the feature flag in `superset_config.py`:
+
+```python
+FEATURE_FLAGS = {
+    "ALERT_REPORTS": True,
+    "ALERT_REPORT_WEBHOOK": True,
+}
+```
+
+#### Configuring a Webhook Recipient
+
+When creating or editing an alert or report, select **Webhook** as the notification method and enter your endpoint URL.
+
+#### Payload Format
+
+Superset sends an HTTP POST with `Content-Type: application/json`:
+
+```json
+{
+  "name": "My Alert",
+  "header": {
+    "notification_format": "JSON",
+    "notification_type": "Alert",
+    "notification_source": "Alert",
+    "chart_id": 42,
+    "dashboard_id": null
+  },
+  "text": "Alert condition met: value exceeded threshold",
+  "description": "Monthly revenue dropped below target",
+  "url": "https://your-superset-host/superset/dashboard/1/"
+}
+```
+
+When a report includes file attachments (CSV, PDF, or PNG screenshots), the request is sent as `multipart/form-data` instead. In that case, each top-level payload field (`name`, `text`, `description`, `url`) becomes its own form field, and nested structures like `header` are serialized as a JSON-encoded string in their own field. Every attachment is added as a repeated form field named `files`:
+
+```
+POST /webhook HTTP/1.1
+Content-Type: multipart/form-data; boundary=...
+
+--...
+Content-Disposition: form-data; name="name"
+
+My Alert
+--...
+Content-Disposition: form-data; name="header"
+
+{"notification_format": "JSON", "notification_type": "Alert", ...}
+--...
+Content-Disposition: form-data; name="text"
+
+Alert condition met: value exceeded threshold
+--...
+Content-Disposition: form-data; name="files"; filename="report.csv"
+Content-Type: text/csv
+
+<file bytes>
+--...
+```
+
+Webhook consumers should branch on `Content-Type`: parse the body as JSON when `application/json`, or read the individual form fields (decoding `header` as JSON) when `multipart/form-data`.
+
+#### HTTPS Enforcement
+
+To require HTTPS webhook URLs (recommended for production), set:
+
+```python
+ALERT_REPORTS_WEBHOOK_HTTPS_ONLY = True
+```
+
+When enabled, Superset rejects webhook configurations that use `http://` URLs.
+
+#### Retry Behavior
+
+Superset automatically retries webhook deliveries on `429 Too Many Requests` and `5xx` server errors using exponential backoff.
+

+## Security Configuration
+
+### HASH_ALGORITHM
+
+Controls the hashing algorithm used for internal checksums and cache keys (thumbnails, cache keys, etc.). The default is `sha256`, which satisfies environments with stricter compliance requirements (e.g., FedRAMP). Set it to `md5` to retain the legacy behavior from older Superset deployments:
+
+```python
+HASH_ALGORITHM = "sha256"  # default; set to "md5" for legacy behavior
+```
+
+A companion `HASH_ALGORITHM_FALLBACKS` list (default: `["md5"]`) lets UUID lookups fall back to older algorithms, which enables gradual migration without breaking existing entries. Set it to `[]` for strict mode (use only `HASH_ALGORITHM`).
+
+:::note
+This setting affects internal Superset operations only, not user passwords or authentication tokens. Changing it in an existing deployment may invalidate cached values but does not require a database migration.
+:::
+
+## SQL Lab Query History Pruning
+
+SQL Lab query history is stored in the metadata database and is **not** pruned by default. To trim older rows, enable the `prune_query` Celery beat task by uncommenting it in `CELERY_BEAT_SCHEDULE` and choosing a retention window:
+
+```python
+CELERY_BEAT_SCHEDULE = {
+    "prune_query": {
+        "task": "prune_query",
+        "schedule": crontab(minute=0, hour=0, day_of_month=1),
+        "kwargs": {"retention_period_days": 180},
+    },
+}
+```
+
+Adjust `retention_period_days` to control how long query rows are kept. Companion opt-in tasks (`prune_logs`, `prune_tasks`) exist for pruning the logs and tasks tables; see the commented-out examples in `superset/config.py`. Without enabling these tasks, the metadata database will grow unbounded over time.

+
+Superset validates theme JSON when it is saved, either through the UI or via configuration.

+### API Key Authentication
+
+Superset supports long-lived API keys for service accounts, CI/CD pipelines, and programmatic integrations (including MCP clients).
+
+#### Enabling API Key Authentication
+
+API key authentication is **disabled by default**. To turn it on, set the Flask-AppBuilder config value in `superset_config.py` and also enable the matching feature flag so the management UI is exposed:
+
+```python
+FAB_API_KEY_ENABLED = True
+
+FEATURE_FLAGS = {
+    "FAB_API_KEY_ENABLED": True,
+}
+```
+
+The config value registers the `ApiKeyApi` blueprint on the backend; the feature flag controls whether the UI for managing keys appears for the user. See the [Feature Flags](/admin-docs/configuration/feature-flags) documentation for more on feature flag configuration.
+
+#### Creating an API Key
+
+Once enabled, each user manages their own keys from their profile page:
+
+1. Open the user menu (top-right) and click **Info** to navigate to the User Info page
+2. Expand the **API Keys** section
+3. Click **+ API Key**
+4. Enter a name and (optionally) an expiration date
+5. Copy the generated token — it is shown only once
+
+Only users with the `can_read` and `can_write` permissions on `ApiKey` (granted by default to Admins) can manage API keys.
+
+#### Using an API Key
+
+Pass the key as a Bearer token in the `Authorization` header:
+
+```
+Authorization: Bearer <your-api-key>
+```
+
+This works for all REST API endpoints and the MCP server. The request is executed with the permissions of the user who created the key.
+
+#### Use Cases
+
+- **CI/CD pipelines** — automated chart/dashboard exports and imports
+- **MCP integrations** — connect AI assistants without interactive login
+- **External services** — dashboards embedded in other applications
+- **Service accounts** — long-lived credentials that don't expire with session cookies
+
+:::caution
+Store API keys securely. Anyone with a valid key can make requests on behalf of the creating user. Revoke keys promptly if they are compromised by deleting them from the **API Keys** section of your User Info page.

+### Semantic Layers
+
+Extensions can register custom semantic layer implementations that allow Superset to connect to external data modeling frameworks. Each semantic layer defines how to authenticate, discover semantic views (tables/metrics/dimensions), and execute queries against the external system.
+
+```python
+from superset_core.semantic_layers.decorators import semantic_layer
+from superset_core.semantic_layers.layer import SemanticLayer
+
+from my_extension.config import MyConfig
+from my_extension.view import MySemanticView

+    id="my_platform",
+    name="My Data Platform",
+    description="Connect to My Data Platform's semantic layer",
+)
+class MySemanticLayer(SemanticLayer[MyConfig, MySemanticView]):

+
+    def get_semantic_view(self, name: str, additional_configuration: dict) -> MySemanticView:
+        # Return a specific view by name
+        ...
+```
+
+**Note**: The `@semantic_layer` decorator automatically detects context and applies appropriate ID prefixing:
+
+- **Extension context**: ID prefixed as `extensions.{publisher}.{name}.{id}`
+- **Host context**: Original ID used as-is
+
+The decorator registers the class in the semantic layers registry, making it available in the UI for users to create connections. The `configuration_class` should be a Pydantic model that defines the fields needed to connect (credentials, project, database, etc.). Superset uses the model's JSON schema to render the configuration form dynamically.

+## Handlebars Chart
+
+The Handlebars chart lets you render query results using a custom [Handlebars](https://handlebarsjs.com/) template. This gives you full control over how your data is displayed — from simple tables to rich HTML layouts.
+
+### Basic Usage
+
+In the chart editor, write a Handlebars template in the **Template** field. Your query results are available as `data`, an array of row objects.
+
+```handlebars
+{{#each data}}
+  <p>{{this.name}}: {{this.value}}</p>
+{{/each}}
+```
+
+### Built-in Helpers
+
+Superset registers several custom helpers on top of the standard Handlebars built-ins.
+
+#### `dateFormat`
+
+Formats a date value using [Day.js](https://day.js.org/) format strings.

+```
+
+---
+
+#### `formatNumber`
+
+Formats a number using locale-aware formatting.

+### Helpers from just-handlebars-helpers
+
+Superset also registers all helpers from the [just-handlebars-helpers](https://github.com/leapfrogtechnology/just-handlebars-helpers) library. These include a wide range of comparison, math, string, and conditional helpers. Commonly used ones include:
+
+#### Comparison
+
+| Helper | Description | Example |
+|--------|-------------|---------|
+| `eq` | Strict equality | `{{#if (eq status "active")}}` |
+| `eqw` | Weak equality | `{{#if (eqw count "5")}}` |
+| `neq` | Strict inequality | `{{#if (neq role "admin")}}` |
+| `lt` | Less than | `{{#if (lt score 50)}}` |
+| `lte` | Less than or equal | `{{#if (lte score 100)}}` |
+| `gt` | Greater than | `{{#if (gt price 0)}}` |
+| `gte` | Greater than or equal | `{{#if (gte age 18)}}` |
+
+#### Logical
+
+| Helper | Description | Example |
+|--------|-------------|---------|
+| `and` | Logical AND | `{{#if (and isActive isVerified)}}` |
+| `or` | Logical OR | `{{#if (or isAdmin isMod)}}` |
+| `not` | Logical NOT | `{{#if (not isDisabled)}}` |
+| `ifx` | Inline conditional | `{{ifx isActive "Yes" "No"}}` |
+| `coalesce` | Returns first non-falsy value | `{{coalesce nickname name "Anonymous"}}` |
+
+#### String
+
+| Helper | Description | Example |
+|--------|-------------|---------|
+| `capitalize` | Capitalizes first letter | `{{capitalize name}}` |
+| `uppercase` | Converts to uppercase | `{{uppercase status}}` |
+| `lowercase` | Converts to lowercase | `{{lowercase email}}` |
+| `truncate` | Truncates a string | `{{truncate description 100}}` |
+| `contains` | Checks if string contains substring | `{{#if (contains tag "urgent")}}` |
+
+#### Math
+
+| Helper | Description | Example |
+|--------|-------------|---------|
+| `add` | Addition | `{{add a b}}` |
+| `subtract` | Subtraction | `{{subtract total discount}}` |
+| `multiply` | Multiplication | `{{multiply price quantity}}` |
+| `divide` | Division | `{{divide total count}}` |
+| `ceil` | Ceiling | `{{ceil value}}` |
+| `floor` | Floor | `{{floor value}}` |
+| `round` | Round | `{{round value}}` |
+
+For the full list of available helpers, see the [just-handlebars-helpers documentation](https://github.com/leapfrogtechnology/just-handlebars-helpers).
+
+### Tips
+
+- Use raw blocks to escape Handlebars syntax if you need to display double curly braces literally.
+- Comparison helpers like `eq` must be wrapped in a subexpression when used with `#if`: `{{#if (eq myVal "foo")}}`.
+- HTML output is sanitized by default based on your Superset configuration (`HTML_SANITIZATION`).
