feat(audio-player): gear-menu default speed + split shortcuts into Mouse/Touch (plan §12)

The Player settings popover gains a 'Default playback speed' row
beside autoplay — a compact rate select, always visible (the Speed ▾
footer hides when current == default, which made the setting
undiscoverable at 1x/1×); same setDefaultSpeed PUT. The shortcuts
dialog splits its pointer section into MOUSE (click/drag/shift/wheel)
and TOUCH (drag/pull-away) — the bar has two scrub systems and the
sections now say so.
