fix: Remove duplicate menu entry and reduce code complexity

- Removed duplicate 'Download Full Album' context menu entry
- Refactored on_download_all_albums_from_playlist to reduce C901 complexity
- Extracted helper methods: _extract_album_ids_from_tracks, _load_albums_with_rate_limiting, _validate_session, _handle_album_load_error, _queue_loaded_albums
- All make check errors and warnings now resolved
