feat(web): 技术信息折叠、原因码人话化、待处理「指定作品」(DEAI-2)

- 新增 TechInfo 折叠组件(默认收起,标题「技术信息」);设置新增「界面」分区,
  「默认展开技术信息」开关存本机浏览器
- 原因码表 @umt/contracts reasons.ts(identity_unknown、blocked:target_exists、below_min_size…
  → 一句人话 + 下一步),服务端整理记录 message 与冲突事项标题/摘要改用它
- 整理记录列表/详情、下载详情与时间线:原码、ID、hash、用时、变更序号进技术信息;
  下载完成但入库失败时单独提示;时间线只列有记录的阶段,标题改「经过」
- 待处理:没识别出作品类事项主按钮「指定作品」(搜媒体库 + TMDB,走已有 resolve;
  整理类事项打开重新整理),忽略为次要;去掉正常态徽章与「实时」指示;原始证据改「详细信息」进技术信息
- 整理成功后同时关闭该下载的「没识别出作品」事项
