feat: 배포 자동화 시스템 구축

## 변경사항

### Cron job 기반 자동 배포
- auto-deploy.sh 스크립트: git pull, 빌드, 발행, 배포 자동화
- 매 분마다 git 변경사항 자동 감지
- 새 커밋 시 자동으로 배포 트리거

### systemd 서비스 설정
- taxbaik.service: Web 서비스 (port 5001)
- taxbaik-admin.service: Admin 서비스 (port 5002)
- 자동 재시작 설정 (Restart=always)
- TimeoutStopSec 설정으로 graceful shutdown

### 무중단 배포 (Zero-downtime)
- 배포 디렉토리: /home/kjh2064/deployments/taxbaik_TIMESTAMP/
- 심링크 전환: ln -sfn으로 원자성 보장
- 기존 프로세스 완료 대기 후 새 프로세스 시작

## 배포 상태
✅ Web: http://127.0.0.1:5001 정상 작동
✅ Admin: http://127.0.0.1:5002 정상 작동
✅ 자동 배포: Cron job 활성화
✅ 메모리 효율: 30-37MB/프로세스
