Move/Copy like Fusion: opens with nothing moved and a full triad at the bodies' centre (X/Y/Z arrows, plane squares, rotation rings, free-drag centre ball; snapped drags, Alt/Ctrl free), Move Type (Free Move, Translate, Rotate, Point to Point, Point to Position), X/Y/Z distances and angles with live preview, a pivot input; the triad is one shared module (gizmo.rs); UI scenario s27
