feat(storyboard): 故事板改分镜制(单场独立重跑/历史)+ 视频过审闸 + 审核前端如实化

三块改动在 services/views/pipeline/App/api 等文件按行交织、且过审闸后端依赖故事板新
模型,无法拆成各自独立可编译的提交,故合并为一次:

· 故事板分镜制:新增 StoryboardShot/StoryboardShotVersion(对标 VideoSegment/Version)
  + 数据迁移(采用版每帧转一 shot+已采用版本)。每镜一个 shot,各自历史版本,可单场
  重跑、逐场切换/采用,新增「开始生成故事板/单场重跑/采用某版」端点。重跑非阻塞(后台
  静默轮询出图,不锁其它场按钮);历史「查看」与「采用」分离(切版本不丢在制重跑)。
  视频取分镜图/删分镜清理/过审闸全部改读 storyboard_shots。
· 视频生成前过审闸:点生成校验含真人脸的人物立绘/故事板分镜是否过审,未过审弹窗列出
  哪一镜/哪个,可一键送审,挡住不生成(collect_video_review_blockers + precheck 端点)。
· 审核前端如实化:不再 `|| "processing"` 伪造审核中;送审失败经 onNotify 如实提示;
  审核轮询扩到视频阶段,送审后能看着盾变绿。
