feat(lidarr): ask Lidarr for release groups; repair stored release-id requests (M483 #5244)

Lidarr's metadata is keyed by MusicBrainz release group, but re-acquisition
requested albums by their release id, so every add came back "not found".

- Sweeper requests an album by its tag-supplied release group, else the one
  MusicBrainz names (cached onto the album). An album MusicBrainz cannot name
  is skipped and counted, with no attempt spent.
- Reconciler: an add refused as not found re-reads the request's album id as
  a release (library first, then MusicBrainz), rewrites the request to the
  group and adds again. This repairs the requests already stored.
- Completion matches an album by release id or release group, and only once a
  track of it is on disk, so a re-acquisition request no longer completes
  against the row of the album it is trying to bring back.

Closes #5241.
