feat: Lidarr searches for a better copy of a rip that has none (M498 #5447)

The operator chose option 2: an album holding a video rip that is the only
copy of its song is searched in Lidarr (AlbumSearch), at most once a week
and ten albums a pass. Lidarr grabs only when the quality profile allows an
upgrade, so nothing is removed and the rip stays held back either way.

- lidarr.Client.SearchAlbums posts the AlbumSearch command.
- ListAlbumsWithSoleCopyRips finds the albums: a held-back rip with no
  present clean copy sharing its song or its pending group, and not searched
  in the last week (audit action lidarr_rip_search).
- Suspect sources shows when Lidarr last searched the track's album.
