feat(web): 记录抽屉与两层导航标准

控制台导航最多两层(侧栏一项 = 一页,页内最多一层页签 / 分段);从列表打开的
记录改成列表页上的右侧抽屉,打开的记录写在 ?open=,刷新、分享、前进后退都能还原,
后退就是关抽屉。标准写在 docs/design/console-ia.md §9,ui-controls.md 引用。

- DetailSheet 加 xl 宽度、标题下操作行;抽屉里再开的 DetailSheet 在同一抽屉里换成子视图(返回 / Esc)
- record-sheet.tsx:useRecordSheet / RecordLink / useOpenRecord / recordPath / taskPath
- 整理记录、订阅、站点(含页签)、下载、日志任务改成抽屉;旧业务任务 / 下载任务 id 在任务抽屉里换算
- 回收站并进文件管理右侧视图(?view=trash);设置左栏只列分区
- 规则组、策略版本、媒体库未识别 / 外部身份、设置实例编辑走 ?open=
- 旧地址 /console/{organize,subscriptions,sites,downloads}/:id、/tasks/:id、/files/trash 跳到列表页抽屉
- 站内链接、铃铛、命令面板、任务时间线改拼新地址;冒烟按 ?open= 检查抽屉
