feat(ui): D.2b — toolbar collapse-to-one-row (bottom-edge snap resize hides/shows row 2)

Browse source 
UiElement.MaxHeight + ResizableEdges mask; UiCollapsibleFrame snaps height to the nearer
of {collapsed,expanded} and toggles row-2 visibility; GameWindow computes the two heights
from the layout + top-anchors the content. Amends IA-17. UiNineSlicePanel unsealed to
allow subclassing.
