[enhancement]: Support toggling Album/Track view for gneres (#591)

* [enhancement]: Support toggling Album/Track view for gneres

The _primary_ purpose of this PR is to enable viewing tracks OR albums for genres.
This has a few requirements:
1. Ability to set default route for genres, **except** when already on song/album page
2. Ability to toggle between album and genre view
3. Fixed refresh for genre ID

Additionally, there was some refactoring:
- Since the *-list-headers had very similar functions for search, export that as a hook instead

* also use hook for album artist

* support switching albumartist tracks/albums

* remove toggle on song/album list, simplify logic
