fix(docker): adapt Dockerfile.prod for Next.js 16 standalone output structure

- Fix standalone path: dist/standalone/novalon-website/
- Update static files path: dist/static
- Replace curl with wget in health checks (Alpine compatibility)
- Add monitoring and optimization scripts
- Configure external network for docker-compose

This resolves the deployment failure caused by Next.js 16's new standalone output structure.
