xfy b734e26645 Replace button-triggered collapse with vertical drag gesture
ViewModel now exposes onDrag/onDragEnd so BottomCard drives the
collapse animation via detectVerticalDragGestures instead of a
discrete collapse() call. Drag maps to 0–1 progress over 200dp;
on release the animatable snaps to the nearest end with spring.
