Add context-aware component search suggestions

[Mbeaulne]

Description

Replaces the static list of hardcoded component search suggestions with a dynamic buildComponentSearchSuggestions function that derives suggestions from the loaded component index. Suggestions are scored and ranked based on common input/output types (highest weight), registered source labels, and component name tokens, with curated fallback defaults when the index is sparse. Each suggestion now carries a kind field ("type", "source", "name", or "default") and a suggestion_position index, both of which are emitted in tracking events instead of the previous suggested_query field. Suggestions that overlap with the current query are filtered out, and the empty-state help text is updated to reflect that suggestions are derived from loaded sources.

Test Instructions

1. Open the component search panel in the editor or dashboard with no query entered and verify that the empty-state suggestion chips reflect types and source labels from your loaded component libraries rather than always showing the same four hardcoded terms.
2. Enter a partial query (e.g. csv) and confirm that csv no longer appears as a suggestion chip.
3. Load a registered component library and verify its label appears as a suggestion chip.
4. Confirm that tracking events for suggestion clicks now include suggestion_kind and suggestion_position instead of suggested_query.
5. Run the unit tests in componentSearchSuggestions.test.ts to verify scoring, source label inclusion, and fallback behaviour.

Additional Comments

The COMPONENT_SEARCH_EMPTY_STATE_SUGGESTIONS constant has been removed. The ComponentSearchEmptyStateSuggestions component no longer sources suggestions internally; callers are now responsible for passing a suggestions prop, which allows each surface (dashboard v2 and editor v2) to supply index-aware suggestions independently.
