[Synology / QNAP / Linux NAS 배포 방법]

1. 이 폴더의 모든 파일 (d3ro-voice-api.tar, docker-compose.yml, .env, nas-control.sh)을
   NAS의 Docker 작업 폴더 ($NasPath)에 업로드합니다.

2. NAS SSH 터미널에 접속하여 해당 폴더로 이동합니다:
   cd $NasPath

3. Docker 이미지를 로드합니다:
   docker load < d3ro-voice-api.tar

4. 서비스를 시작합니다:
   docker compose up -d

5. 브라우저에서 접속 확인:
   - 포털 메인: http://<NAS_IP>:$Port/
   - 관리자 백오피스: http://<NAS_IP>:$Port/admin
   - API Swagger: http://<NAS_IP>:$Port/swagger
   - 헬스체크: http://<NAS_IP>:$Port/health
