music (web): click the dock track info to open its album in /music

The bottom player dock's cover + title/artist is now a button — clicking it sets
the music:cwd channel to the playing album and navigates to /music, landing on
that album's tracklist (current track highlighted). Uses the global panel
channel + react-router navigate.
