feat(phase2): 追更/授权链/跨省复用/终端抽检/CI(F21/F22/F13/F08/K)

- F21 追更: AddEpisodes 追加新集不重新发码; Merkle定位变更集
- F22 授权链: RecordAuthorization + CheckAuthorization(地域/平台/期限), 嵌入注入前核验
- F13 跨省复用: CrossProvinceAdmit 三重校验(MA有效+哈希一致+非黑名单)快速准入
- F08 终端抽检: TerminalVerifySegment 片段校验+断流提示
- K.1 CI: .gitlab-ci.yml(后端构建/测试/前端构建)
- 新增6个API; 16项测试通过; 二期纯代码功能全部完成
- A(真实链)/B(BFF)延后至有环境/三期, MemoryChain接口已就绪可平滑替换
