refactor: Strengthen deploy-prod.yml with comprehensive checks and logging

【 개선사항 】
1. Build 단계 분리: metadata 생성, artifact 관리
2. Pre-deployment 검증: SSH, secrets, artifact, connectivity
3. 실제 배포: SSH를 통한 원격 배포, symlink 관리
4. 헬스 체크: 10회 재시도, 상세 검증
5. 배포 후 검증: 실제 서비스 상태 확인
6. 완벽한 에러 처리: 각 단계별 fail-fast
7. 배포 결과 리포팅: 성공/실패 알림

【 구조 】
- Build: .NET 빌드 + 아티팩트 생성
- Pre-deploy-check: SSH/Secrets/Artifact/Connectivity 검증
- Deploy: 실제 배포 + 헬스 체크
- Post-deploy: 배포 결과 리포팅
