refactor(docker): improve Docker setup and reduce image size

- Add multi-stage build to Dockerfile for smaller production image
- Move docker-compose.yml to project root for easier usage
- Flatten docker/init/setup.sh to docker/setup.sh
- Expand .dockerignore to exclude unnecessary files
- Remove deprecated version field from compose files
