Igor Loskutov 009590c080 feat: search frontend (#551)
* feat: better highlight

* feat(search): add long_summary to search vector for improved search results

- Update search vector to include long_summary with weight B (between title A and webvtt C)
- Modify SearchController to fetch long_summary and prioritize its snippets
- Generate snippets from long_summary first (max 2), then from webvtt for remaining slots
- Add comprehensive tests for long_summary search functionality
- Create migration to update search_vector_en column in PostgreSQL

This improves search quality by including summarized content which often contains
key topics and themes that may not be explicitly mentioned in the transcript.

* fix: address code review feedback for search enhancements

- Fix test file inconsistencies by removing references to non-existent model fields
  - Comment out tests for unimplemented features (room_ids, status filters, date ranges)
  - Update tests to only use currently available fields (room_id singular, no room_name/processing_status)
  - Mark future functionality tests with @pytest.mark.skip

- Make snippet counts configurable
  - Add LONG_SUMMARY_MAX_SNIPPETS constant (default: 2)
  - Replace hardcoded value with configurable constant

- Improve error handling consistency in WebVTT parsing
  - Use different log levels for different error types (debug for malformed, warning for decode, error for unexpected)
  - Add catch-all exception handler for unexpected errors
  - Include stack trace for critical errors

All existing tests pass with these changes.
