Completes the five Favorites tabs. Both lazy-load like the others.
Playlists:
- Sourced from QbzCore::get_user_playlists (the getUserFavorites
envelope has no playlists branch; Tauri splits owned-vs-following
locally — the MVP shows the full user playlist list for now).
- FavoritePlaylistItem card: cover (images300 > images150 >
images, first entry), name, "N tracks". Cover streams via the
artwork pipeline (new ArtworkTarget::FavoritePlaylist). Click is
logged — no playlist detail view in the Slint MVP yet.
Labels:
- Parsed from get_favorites("labels"); the qbz-models Label is
just {id,name}, so a local FavLabel shape picks up the
albums_count. FavLabelRow (icon + name + "N releases") routes
the click into the existing LabelReleasesView via
FavoritesActions::open-label -> navigate_label.
FavTab gains Playlists + Labels; from_route/from_tab_id now resolve
them so the header dropdown and tab bar both lazy-load. Tab bar
shows live counts for all five tabs.
Still deferred (per "finish then polish one by one"): the richer
Tauri options (sort, group-by-artist, owned/following split,
per-row context menus, bulk select, download status).
