feat: guna MySQL external — host.docker.internal (dev) & 172.17.200.16 (prod)

- Buang service db dan volume dbdata dari compose files
- dev: extra_hosts host.docker.internal:host-gateway → capai MySQL Windows host
- prod: IP terus 172.17.200.16, tiada extra_hosts diperlukan
- .env.docker: DB_HOST=host.docker.internal dengan nota untuk production
- entrypoint.sh: default DB_HOST → host.docker.internal
