chore(golden): принять рамку выделенной лестницы (#676)

Linux CI 36320878644 на 193d7b0d подтвердил ровно одну ожидаемую сцену:
stairs-flat-selected-light — рамка узлов лестницы в верхнем оверлее с
бусинами сторон и вынесенным узлом вращения вместо прежних узлов под
стенами. Остальные 183 сцены, включая три лестничные, без изменений.
Отпечаток исходников после ребейза на dev тот же (#655 — только бэкенд),
поэтому артефакт того прогона принят как есть.

Issue: #676
