fix(post-p95): 编辑态按钉住版渲染，自填/代填主体展示改判 submitter

- 跨版本编辑必挂：编辑态此前吃 resolve 返回的当前发布版渲染，服务端却按答卷钉住
  的旧版校验，升版后编辑永远 400。改为拉 /my/detail 取钉住版 groups，渲染与校验
  同源（renderGroups）。
- 自填行 subject 归一为本人后，"本人自填"与"他人代填"的判据从"subject 是否为空"
  改为"subject 是否等于 submitter"，同步修正 My.vue / Data.vue / AnswerDetail.vue
  三处展示与 tooltip。

验证：type-check + build 双绿。
