Subject: [PATCH] fix(deploy): proxy /deepflow-backend/* to backend /api/* in
 Docker + expose deepflow ports

- next.config.js: server-side rewrites so the standalone frontend (built with
  NEXT_PUBLIC_API_URL=/deepflow-backend) can reach deepflow-backend:8000/api/*
  without CORS; target overridable via DEEPFLOW_BACKEND_HOST
- docker-compose: expose deepflow-frontend 3001:3000 and deepflow-backend 8000:8000
