BOHA c997a22a3c perf(mui): smooth theme cross-fade via View Transitions API (was per-element repaint jank) ...

The per-element color/box-shadow transition repainted the whole tree every frame (~5fps). Replaced with document.startViewTransition: the browser cross-fades one GPU-composited snapshot of the page — smooth regardless of element count. flushSync + useLayoutEffect ensure the data-theme flip is captured in the transition; instant fallback where unsupported / reduced-motion.
