fix: 清单4 未完成项二轮(视频项目收口/选用角色/场景空镜/场景刷新 + 4:5 尺寸)

ZWQ#15 视频进度卡 3/4(真因补全):
- current_stage 没推到 VIDEO 时 settle 守卫直接返回 → 永不收口。
  submit/poll/adopt 幂等补推 current_stage→VIDEO;进详情(retrieve)检测全段已出片即自愈收口。
  存量卡死项目一打开就自动变「已完成」。+2 测试

ZWQ#7 演员库选用角色未自动「已过审/已采用」:
- 真实流程是 attach(选用),非详情弹窗按钮。attach 时显式置 adopt=adopted +
  人物立绘自动送审(on_commit)。+1 测试

ZWQ#13 场景出真人致视频被拒(加强):
- 场景空镜约束改为显式压过脚本描述里的人物词(「即使上文提到人也只画环境」)。

ZWQ#17 场景生成中刷新跳新窗口:
- 正在生成的场景草稿不再落盘 → 生成中刷新页面不会与新实体卡并存成两个窗口。

附:平台套图 4:5 尺寸 1664x2080→1728x2160(≥Seedream 5.0 最小面积 3686400px,否则 ARK 退 400)。
