Fix favorites not persisting after navigation

- Replace invalid 'music/album' API command with 'music/item_by_uri'
- Use album URI to fetch fresh favorite status on album screen load
- Invalidate home cache when favorite is toggled so home screen
  shows updated status

Fixes issue where favorites would appear in search/library but
not persist on home screen due to stale cached data.
