Show compilation albums under individual artists

Is your feature request related to a problem? Please describe.
I have a lot of albums from various artists (using the compilation tag TCMP), but I noticed those albums don't show up under the individual artists of the compilation.

Describe the solution you'd like
Also show the albums under each artist that contributed

Hide artists without albums

Additional context

How it shows in Navidrome:

The problem is less individual artists on tracks, but rather artists co-credited towards albums. Navidrome returns all albums an artist is credited to (this is reflected in albumCount, so we can't filter these), even if they aren't the primary contributor, but our database schema only handles a single artist "owning" an album.

I have a minor fix (435137b) for some weirdness related to this coming, but the real solution is a schema overhaul to support Navidrome BFR/modern OpenSubsonic in general.
