Improve tag autocomplete with bounded cached search

[niemyjski]

Tag autocomplete now shows up to 250 organization-wide suggestions and searches beyond that initial set without discarding selected tags. Complete results filter locally; incomplete results use debounced, bounded literal searches through the existing aggregation endpoint. Results are cached for five minutes per session, organization, and search; dashboard filter changes do not refetch suggestions.

Completeness follows the pinned repository's typed bucket metadata and zero-counter omission contract, covered by backend tests. Authorization, retention, premium checks, and public API contracts remain unchanged.

Validation:

• 11 focused frontend unit tests and 6 backend integration tests passed.
• 2 browser regressions passed, covering local filtering, debounce, cache reuse, retry, preserved selections, and no requests after date/project changes.
• Real local API/browser verification found a rare punctuation-containing tag beyond the initial 250.
• npm run validate passed; maintainability review has no outstanding findings.
• A small synthetic 2,301-event fixture returned bounded queries in approximately 4–8 ms across five warm runs per query; this is not production-scale load evidence.

No breaking changes.

Clear the search text when closing the tag picker

When a user types a query and closes the picker, this branch clears only debouncedSearch; the bound search state retains the query. Reopening the picker therefore immediately filters the suggestions by the previous text and may launch another remote lookup instead of showing the full tag list as it did previously. Reset search when open becomes false.
