Fix: wheel over UI scrolls the list instead of zooming the camera

Browse Source 
The orbit rig read the wheel unfiltered for zoom, so scrolling a paint-mode
scroll list also zoomed the camera. Gate the zoom behind a shared
InputUtil.PointerOverUi() helper (EventSystem raycast); MeshPainter's private
IsPointerOverUi() now delegates to the same helper (DRY).
