 ### Task 20: 访客列表页
 
+**执行约定（Task 18/19 审查沉淀）**：① 详情路由 keepAlive=true——detail.vue 必须在 `onActivated` 或 watch `$route.query.visitor_id` 里响应访客切换，不能只在 setup 读一次；② 访客列表是分页表——useTable 用语义化方法（`refreshCreate`/`refreshUpdate`）而非裸 `refreshData`；③ `formatDateTime` 从 site/index.vue 提取到共享 util（`admin/src/utils/` 下 tracker 模块）供列表/详情复用；④ 后端时间戳已统一 `timezone.localtime().isoformat()`（上海时间），前端直接展示；⑤ 筛选请求带竞态守卫（reqSeq 令牌，参照 dashboard 修法）。
