fix: add PointerEvent fallback for swipe detection

Browse Source 
touchstart/touchend never fire on this device (confirmed by zero [TOUCH]
log entries). The activity tracker already uses pointerdown/pointerup and
works fine, proving PointerEvents reach the preload. Added pointer event
handlers that mirror the touch handlers for all gestures (2-finger swipe,
3-finger toggle, 1-finger arrow keys). A 500ms debounce on the IPC send
prevents double-firing on devices where both event types fire.
