feat(backend): model albums in the domain

Album is abstract with UserAlbum as its first table-per-type child, the same split Track already uses, so the YouTube albums can join later without moving anything. Tracks are linked through AlbumHasTrack rather than a column on the track itself: an external track is shared between users and the same song shows up in more than one album.
