fix: ghost border, track buttons clickable, per-track instrument silent

- Remove dashed border from ghost notes (fill-only at 25% opacity)
- Track column: replaced div overlay with natural flex child; use
  <button> elements with border-l-2 indicator; removed pointer-events
- Ghost playback: skip layers with no instrument assigned (silent)
  instead of playing with default piano
