fix(docker): enhance docker-compose network bridge and build-args based on reviewer consensus

- Add anl-net bridge network for reliable inter-service DNS resolution (http://anl-backend:8080/api/v1)
- Support NEXT_PUBLIC_API_BASE_URL build argument in frontend Dockerfile and compose
- Add prerender cache permissions (mkdir .next && chown nextjs:nodejs) in refer_landing_page/Dockerfile
- Add root .env.example with documented port and token configurations
- Add backend/.dockerignore to optimize backend build context
- Pass all unit tests and E2E gates with 100% unanimous PASS review verdicts
