feat(web): player bar, playable track lists and Collection (M3)

- player bar with cover, like and dislike, previous / play / next,
  shuffle, repeat, seek bar and volume; PlayerProvider lives with the
  signed-in shell and restores the last track and position paused
- clicking a row (or Enter) plays the list from that track with its
  context (album, search, history, collection); the current track is
  highlighted and rows have a like button; a reaction refreshes lists
- Collection: history grouped by day with clearing, likes with "play
  all" and dislikes, all with paging; sidebar section
- events and playback state are flushed when the page is hidden;
  player timers survive StrictMode remounts
