feat(quarantine): show real audio quality in the review UI + path-resolve diag

- list_quarantine_entries now surfaces the probed quality (context._audio_quality,
  recorded before the gates) so each quarantine row shows what the file actually
  is when deciding to approve/delete. Rendered as a quality chip in the review UI.
- _resolve_library_file_path logs the searched base dirs once when it can't
  resolve a path, so a remaining mount/path mismatch is diagnosable.
