feat(admin): photo upload in album photos tab (same staging pipeline as app)

- 照片页签工具栏加「上传照片」（多选 jpeg/png/heic）→ /v1/uploads
  init → PUT staging → complete（clientTaskId 幂等；categoryId 随当前分类筛选）
- 逐张结果：部分成功语义（成功 N 张 toast + 失败明细前 3 条）；完成后 reload
- 类型 UploadInitPayload/UploadSession/UploadCompleteResponse + api/uploads.ts
- 问题1 修复说明：详情页 404 系并行部署把 2618ad3 server 覆盖回 8e674a9，
  已重滚双栈至 ui06-2618ad3（assets 端点恢复 200，详情页零失败请求）
