rework song rows and now playing, add star to the notification

- star/unstar from the context menu fills the icon, then dismisses
- drop the star badge from album art and song rows
- song rows keep a track-number column (natural order fallback), shrink
  four-digit numbers, and gain right-hand download and duration columns
- the play indicator always sits in the left column, overlaid on cover art
  with an inset primary outline when art is shown
- now playing is left aligned with a star toggle
- the media notification gets a star button backed by a session command
