Add source filter bar to editor component search

[Mbeaulne]

Description

Adds source filtering to the editor's component search panel. The SourceFilterBar component now supports an "icons" display mode that renders compact circular icon-only buttons (instead of full label + count buttons), with tooltips showing the source name, component count, and toggle hint on hover.

The editor's ComponentSearchV2Content renders the SourceFilterBar in "icons" mode, wired up to new state (sourceFilterOptions, disabledSourceKeys, toggleSourceFilter, enableAllSources) exposed by useComponentSearchV2State. Filtering by disabled source keys is applied to lexical matches, AI candidate matches, embedding matches, browse folders, and search suggestions. Resetting the rerank state is also triggered when the source filter changes.

Test Instructions

1. Open the editor and expand the component search panel.
2. Verify that source filter icons appear below the search/rerank controls.
3. Hover over an icon to confirm the tooltip shows the source name, component count, and click hint.
4. Click an icon to hide that source and confirm results update accordingly.
5. Click "Show all" to re-enable all sources.
6. Confirm that switching sources resets any active rerank state.

Additional Comments

The SourceFilterBar display="icons" mode intentionally omits the label and count from the button itself, relying on the QuickTooltip to surface that information, keeping the toolbar compact in the constrained editor sidebar layout.
