feat(ui): new equalizer logo, favicon link, fix star vertical alignment

- icon.svg: replaced music-note with 5-bar equalizer waveform (gold
  gradient on dark bg) — works well as favicon and app icon at all sizes
- index.html: add <link rel="icon"> so browsers pick up the favicon;
  move #btn-star-current out of the title row and into player-track so
  player-track's align-items:center centers it with the full info block
- styles.css: add flex:1 to .player-info base rule; remove stale mobile
  overrides that assumed the star was inside player-info (position:absolute,
  padding-right hack)
