Add Ratings section under General: manual skip count before setting 1★,
and per-axis minimum stars for random mixes/albums (song, album, artist).
StarRating shows five stars with selection capped at three; shared max in authStore.
Queue filtering via passesMixMinRatings; OpenSubsonic-style entity rating fields on types.
