The shared AlbumCard always rendered the favorite heart (overlay button +
"Add to favorites" menu item). Local Library albums are not Qobuz-favoritable
(Tauri's AlbumCardLibraryLite hides favorite/genre), so the upcoming local
grid needs to suppress it.
Add an additive `show-favorite: bool` (default true) on AlbumCard, threaded
through AlbumCollectionView -> AlbumGrid. The fav overlay button uses
`visible:` (not an `if`) so it stays referenceable by `overlay-on` (keeping
the Qobuz hover-no-flicker behavior intact); the menu item is gated with an
`if`. All existing callers (Discover / Favorites / Label) default to true,
so behavior is unchanged.
