fix(favorites): reflect player-bar song star in track lists (#1063)

* fix(favorites): reflect player-bar song star in track lists

Liking a song from the player bar / fullscreen / shortcuts wrote only to
the session `starredOverrides` map, which onStarSuccess deleted once the
server sync resolved. List views (AlbumDetail, Favorites, RandomMix,
playlists) seed their starred state from a one-shot fetch and reflect
later changes only by merging that override, so the row reverted the
instant the sync completed — the like never stuck in the list. Toggling
from a list row also updated the row's own local state, which is why that
direction already worked.

Keep the star override as the durable session source of truth (stop
deleting it on success); the in-memory Track / queue-cache patches stay.
The override is unpersisted and superseded by the next toggle, so it never
diverges from the server. Ratings keep their existing clear-on-success
behavior.
