fix: progress bar smooth via rAF with direct Date.now(), queue panel moved outside player div

- Progress bar reads playStartedAt directly in requestAnimationFrame loop
  bypassing Vue reactivity caching for smooth 60fps updates
- Queue panel moved to sibling of player-bar (was trapped inside causing z-index issues)
- Added progress thumb dot on hover
- Click on progress shows 'seek not available' tooltip
