feat(ui): D.2b-A — BringToFront + raise on show/click

Browse source 
BringToFront sets a window's ZOrder one past the max among its peers.
ShowWindow now raises on open; OnMouseDown raises any pressed top-level
window (retail-faithful stacking). Existing drag/resize tests unaffected
(raise only touches ZOrder, not geometry).
