refactor(render): drop the dead parent_plate_rect text clamp (Phase 6at)

Element::is_plate is constant-false (deleted from cce-ui in the 6at
fold sweep): no widget here claims plate-hood since the Plate
dissolution, so the per-widget plate-ancestor walk and the text-bounds
intersection it fed were dead. A/B on the live compositor: only
unrelated terminal text behind the translucent window differs.
