Replace the old `cache_covers` approach with a new `register_tracks_lazy` method that handles track registration for lazy playback in playlists. The new implementation avoids expensive `get_stream_url` calls by deferring audio URL resolution to `QobuzLazyProvider`, caches covers in parallel with concurrency limited via semaphore (16), and stores full metadata including cover PKs. This significantly improves performance for large playlists while preserving all necessary track metadata.
