Follow-through on 6a0c3d5e (state-visible hearts): the card-level
album 'favorite' arm was still add-only — a filled heart re-added and
toasted 'Added to favorites'. It now toggles, mirroring the header
arm: fav_cache-keyed, optimistic set_album_row_favorite + rollback on
error, cache written on success only, reco logging on ADD only (the
Capa B search-interaction record is now gated to adds, like tracks).
AlbumCard's menu item goes state-conditional (Remove from Library +
filled heart), and the now-playing '+' flyout album entry becomes
state-honest through a new NowPlayingState.album-favorite (seeded per
track in refresh_now_playing_meta, flipped live by
set_album_row_favorite — which now also syncs the open album page's
header heart, closing the stale-header undo loop). Favorites' own
intercepted unfavorite (fade + row removal) is untouched, both view
modes. One msgid x8 locales.
