feat(ui): bulk entity ratings, Random Albums multi-select, album New badge (#446)

Add star rating rows to multi-artist and multi-album context menus so the
selection shares one rating control (mixed ratings show empty until set;
keyboard navigation supported). Pass selectedAlbums into AlbumCard on Random
Albums so multi-select context menu works. Add i18n aria labels for bulk
rating controls. Move the New album badge to the top-right of the cover and
stack it with the offline badge to avoid overlap.
