fix(gacha): park the pointer off the card after tearing the pack

The scripted drag released the mouse over where the card lands. Once the
card arrived under it, pack-cards tilted the hovered card toward the
pointer over its .22s transition, so the face kept moving after the spin
stopped. The pointer now moves to the corner when the drag ends.
