New SongView, UV & More (#6)

Honestly, I don't remember everything I've done in this branch.

Important things:
 - Started using UV for dependency / python version management
 - Fixed the stupid queue skipping bug (still can't believe it was a race condition)
 - New SongView widget that multiple screens share
 - New features on most views with songs!
   - Songs can be shared
   - Songs can be added to playlists
   - Songs can be rated
 - Upgraded my Navidrome server version & had to change some stuff for it
