fix: bottom bar no touch seek; lyrics seek on Android; smoother NP animation

- initProgressScrub: pass noTouch=true for the bottom mini-bar so touch
  events are never registered on it; only mouse events remain (desktop-only).
  The now-playing scrubber is unchanged and keeps full touch support.
- Export seekToMs(ms) from player.js; use it in the lyrics click handler
  instead of S.audio.currentTime which has no effect when HAS_BRIDGE
  (native ExoPlayer handles playback, not the HTML audio element).
- styles.css: add will-change:transform to .player and .np-overlay to keep
  them on GPU compositor layers during the swipe gesture; tweak NP open
  transition to cubic-bezier(.4,0,.2,1) for a snappier feel.
