fix(DragDropSort): enable mobile drag-and-drop support

PointerSensor without an activationConstraint does not distinguish
drag intent from scroll intent on touch devices. Add a distance
constraint of 8px so the drag only activates after deliberate
pointer movement, enabling mobile support via the Pointer Events API.

Fixes #12415
