music (web): cursor-pointer on dock controls (Tailwind v4 no longer defaults it)

Add cursor-pointer to the player dock's buttons — track-info, prev/next (with
disabled:cursor-default), play/pause, mute, and close — and to MusicHeart (so
every heart across the player/tracklists gets it). The volume slider and SeekBar
already had it.
