fix: prevent recording data loss on crashes and restarts

Fixes critical data loss bugs where recordings would be deleted from IndexedDB
on app restart or when Recall SDK crashed during a meeting.

Changes:
- Reset isRecording flag when SDK crashes to allow recovery
- Mark interrupted recordings as 'error' instead of deleting from IDB
- Keep 'ready' recordings in IDB for fast access (user can delete manually)
- Add lastSegmentTime tracking to detect silent failures
- Add Recover/Discard UI buttons for interrupted recordings
- Simplify meeting-detected log output

The architecture now treats IDB as source of truth with non-destructive
operations, giving users full control over interrupted recordings.
