refactor: adapt Separator usage to the cce-ui Phase 5 migration

Separator's rect moved from public x/y/w/h fields onto the Adapted
base: store Vec<Adapted<Separator>> and transpose the vertical-bar
rotation via rect()/set_rect() instead of field swaps. Rendering is
unchanged (rect() + color(), both forwarded by the adapter).
