The heart on a Qobuz playlist detail was wired to Qobuz /favorite/create,
which does not accept playlist_ids, so it persisted nowhere and never
reflected in the library. Rewire it to the INTERNAL library favorite
(db.set_playlist_favorite, mirroring the Favorites card + Tauri's
v2_playlist_set_favorite) and seed it on open.
Add the two missing actions on a non-owned Qobuz playlist:
- Copy to library: clone it (create + add all tracks, carrying the source
artwork + attribution) as an internal owned copy.
- Follow on Qobuz: subscribe/unsubscribe via new qbz-core passthroughs to
the existing client subscribe_playlist/unsubscribe_playlist.
Surface hearted-but-not-owned playlists in Library>Playlists by merging
the internal favorite ids into the manager list (they don't come back
from get_user_playlists). Copies/follows already appear there (owned /
subscribed). New PlaylistState.is-following / is-copied.
