feat: Add Docker Compose setup for fullstack deployment

- Add Frontend Dockerfile with Next.js standalone build
- Add docker-compose.yml for production deployment
- Add docker-compose.dev.yml for development with hot-reload
- Configure Frontend next.config.js with standalone output
- Add .dockerignore files for both backend and frontend
- Add comprehensive README-DOCKER.md documentation
- Update .gitignore to exclude node_modules and build artifacts
- Remove obsolete component files (CycleCalculator.tsx, PHDiagram.tsx)
- Backend and Frontend communicate via Docker network
- Healthchecks configured for both services
- Environment variables configured for API URL
