Update all callers to use matching_records

Migrate StatsLive.Index, ScrobbledTracksLive.Index, and TopAlbums to
consume matching_records list instead of scalar record IDs. Remove the
derive_legacy_record_ids bridge function. TopAlbums now uses a dropdown
for multi-record badges with play count display.
