Complete React migration with WebGL design and comprehensive testing

- Add missing dependencies: react-router-dom, framer-motion, three, @react-three/fiber, clsx, tailwind-merge
- Add TEST_PLAN.md with 50+ test cases across 5 phases
- Add TEST_RESULTS.md with 100% pass rate documentation
- Remove unused kopia-compose.yaml

Features:
- WebGL dot matrix background with glassmorphism UI
- Full i18n support (EN/NL/AR with RTL)
- Code-split Three.js (68% bundle size reduction)
- All functionality preserved (validation, SSE, error handling)
- Docker build tested and passing

Status: Production-ready
