DatasourceControl.test.tsx consistently OOM-crashes Jest workers in CI
(shard 7) because the last 4 tests render the full DatasourceEditor
(2,500+ lines, 150+ imports) without mocking. Each test mounts this
massive tree, compounding memory until crash.
Mock DatasourceEditor with a lightweight stub since these tests only
verify DatasourceControl's callback wiring through the modal save flow,
not editor internals. Also remove stale SupersetClientGet.mockImplementationOnce
calls from 2 earlier tests that leaked unconsumed mocks into subsequent
tests (jest.clearAllMocks doesn't clear mock implementations).
Results: heap 615MB→501MB, test time 33s→20s, heavy tests 5500ms→118ms.

Add test coverage for 5 components that were converted from class to
function components but lacked tests: TTestTable, SpatialControl,
FilterValue, TableRenderers, and FilterScopeSelector (56 new tests).

Prevent runtime error when the API returns an empty tab_tree array
by checking treeData.length before accessing treeData[0].

The test props objects spread from `requiredProps` (typed as
`Partial<ChartRendererProps>`), making `actions` optional. Add type
assertions to match the pattern used by other tests in the same file.

The class-to-function conversion of DatasourceEditor introduced an infinite
re-render loop that prevented the edit dataset modal from becoming interactive,
causing 30s timeouts in Playwright tests.
Root cause: Multiple useEffect hooks fired on mount and triggered
validateAndChange() -> parent onChange() -> parent re-renders with new
propsDatasource reference -> useEffect fires again -> infinite loop.
Fixes:
- Add isInitialMount ref to skip validation effects on first render
(matching original componentDidMount which never called validateAndChange)
- Remove setTimeout(callback, 0) from onDatasourceChange (redundant with
the useEffect that already watches datasource changes)
- Add prevPropsDatasourceRef to prevent useEffect([propsDatasource]) from
re-processing unchanged prop references
- Add isSyncingColumnsFromProps ref to distinguish prop-sync column updates
(which should NOT trigger validation) from user-initiated column changes
(matching original class behavior where componentDidUpdate called setState
without a validation callback)
Also restores missing props in CollectionTable function component:
- filterTerm/filterFields: Client-side collection filtering
- pagination: Controlled pagination config passthrough

SaveModal was converted from a class component to a function component,
which broke tests that were instantiating it with `new TestSaveModal()`.
Changes:
- Extract `createRedirectParams` and `addChartToDashboard` as exported
utility functions that can be tested directly
- Update tests to use the exported functions instead of trying to
instantiate the component as a class
- Add placeholder tests with TODO comments for tests that require
component rendering (onDashboardChange, onTabChange, saveOrOverwrite)

Convert all remaining React class components to function components
using hooks (useState, useCallback, useEffect, useRef, useMemo) to
satisfy the react-prefer-function-component ESLint rule.
Key changes:
- Converted components in dashboard, explore, SqlLab, and Chart areas
- Updated associated test files with proper typing
- Fixed JSX.Element return types for components used as JSX
- Added explicit ControlHeader props where needed
- Fixed shouldFocus callback signature in WithPopoverMenu usage
Notable exceptions (not converted):
- ErrorBoundary (uses componentDidCatch)
- DragDroppable (react-dnd requires class instances)
