Add Match Tracks button and Local/External column to Active Playlists

- Added 'Match Tracks' button to trigger matching for specific playlist
- Added Local/External column (shows '-' for now, will populate after matching)
- New endpoint: POST /api/admin/playlists/{name}/match
- Injects SpotifyTrackMatchingService into AdminController
- UI shows: Name | Spotify ID | Total | Local/External | Cache Age | Actions
- Allows users to manually trigger matching without waiting 30 minutes
