perf: optimize framer-motion bundle size and memoize dictionary fetching

- Wrap getDictionary with React cache to prevent redundant JSON parsing on the server
- Create MotionProvider to globally initialize framer-motion LazyMotion with domAnimation
- Replace standard 'motion' imports with 'm' across all animated client components (HomeClient, Navbar, GaleriClient, SSSClient, card, text-reveal) to drastically reduce First Load JS size
