Album and artist context menus gain an Info dialog covering the plural
album artists, sort names and the play and download details the screens
do not show. Multiple artist links collapse into one ellipsised entry
that opens the artist chooser instead of listing each artist.
Sort lists can now prefer regular names over sort names, or only use
sort names for names without Latin letters. The new plain-name indexes
keep those orders out of a temp B-tree.
Also carry plural artists through the Media3 queue so Now Playing and
the mini player keep them, drop the album artist tap ripple, and show
the aggregate download progress in the tab bar where offline mode used
to sit.
