feat: Admin › Reports is one queue of broken tracks, whether a listener flagged it or it failed to play, one row per track with one set of actions (M503 #5606)

- /admin/reports folds the quarantine queue and the unresolved playback
  errors into one row per track, newest first: who flagged it and why,
  what failed and for whom, the file, with Resolve (clears the reports and
  marks the errors fixed), Play, Copy details, Delete file and, for an album
  Lidarr holds, Delete via Lidarr.
- One delete path: Delete file removes the track, and its reports and
  errors go with the row.
- A Handled tab shows what was done: reports cleared, files deleted,
  errors marked fixed or ignored.
- The summary counts reports by track across both sources, so the rail,
  the Overview and the page agree.
- /admin/quarantine and /admin/playback-errors redirect to Reports: the
  notifications and the Android app link to them.
