chore: split Dockerfile into runtime+e2e stages, add healthchecks

- Split Dockerfile: runtime stage (no Playwright) + e2e stage (adds Chromium)
- Add healthcheck to backend and frontend in docker-compose.prod.yml
- Fix REDIS_URL default to empty string (no hardcoded password)
- Add RATE_LIMIT_BACKEND=redis to production env example
- Remove deprecated version field from docker-compose.prod.yml
