feat(frontend): show transcription + keyword search + channel/date filters + speaker leaderboard
- cards now render transcription snippet (expandable); no-transcript placeholder
- toolbar: search box (transcription+username ILIKE), speaker filter (existing),
channel filter, start/end date range, RESET
- new DECK/LEADERBOARD tabs: leaderboard = per-speaker clips, est duration,
transcribed words (useRecordingsSummary → recordings.summary); click a row
jumps the deck to that speaker's clips
- hooks: filter-driven SWR cache key (fields serialized), representative key
matcher for delete/WS-sync across all filter views; useRecordingsSummary hook
- recordingsApi.list generalized to RecordingListParams (q/startDate/endDate)
