feat: show title/album/artist order in bottom bar and now playing UI

- Bottom bar: player-info is now a centered flex column so text block
  aligns properly against the art circle
- Now playing: split artist·album line into album (above) + artist (below)
  matching the bottom bar layout; removed np-album-sep reference
- Removed stale np-album-sep style.display call from player.js
