The previous scale factor of 5000 made rotation changes too subtle to see.
Reduced to 500 (10x more sensitive) so card rotation is clearly visible
when dragging from off-center grab points.
Also added detailed rotation logging during drag to help debug:
- Shows current rotation angle
- Shows rotation influence being applied
- Shows cross product value from physics calculation
This will help test and tune the rotation feel.
