feat: version list with verification + deployed badge (stage 3)

- pulp_client: list_versions / list_distributions / get_publication
- GET /repos/{uuid}/versions: 버전 목록 페이지(최신순)
- 현재 운영 배포 버전 판별: Distribution→publication→repository_version 역추적
- views.build_version_view: vN, 생성일시, 패키지 수, 증감(+/-), 검증 배지, 배포 여부
- views.verification_detail: gpgcheck/repo-gpgcheck/checksum 상세 (화면4)
- 대시보드 저장소명 → 버전 페이지 링크, [이 버전 배포] 버튼은 단계4용 placeholder
- 단계1 TODO(배포 버전 역추적) 해소
