app接线: 上传去重响应/已存附件删除/缩略图白名单对齐后端 (tsk_sTHRFtFoHf-G)

- createTask 消费后端去重后的权威 attachments 列表，按入库数报数并提示去重数
- 附件删除 toast 语义由 warn 调整为 ok（attDeleted 为成功语义）
- TaskDetail 缩略图 isImg 收敛到 KIT_ATT_SAFE_INLINE 硬白名单(png/jpeg/gif/webp)，
  与后端 src/api/server.ts SAFE_INLINE 一字不差，svg/html 不走 <img src=服务端URL> inline，
  钉死同源存储型 XSS
- i18n 新增 attUploaded/attDeduped 两个带 {n} 占位的 key，覆盖 zh/en/es/ja/fr
