feat(ratings): Subsonic entity ratings and StarRating UX

Probe OpenSubsonic after connect; persist album/artist ratings via setRating when supported. Add shared StarRating (repeat same star to clear, pulse and shrink animations, hover freeze after clear). Widen tracklist duration column and bump narrow saved widths in localStorage. Use StarRating in AlbumHeader, track lists, and playlist rows.
