 * Monitors/TraceItem/Index — 埋点（跟踪项）列表（自定义迁移页）
 *
 * 后端 TraceItemController [Menu(65, false)] 隐藏页，菜单不注册路由，
 * 靠框架 DefaultEntity 的 catch-all + hasMatchingCustomView 自定义视图兜底，可访问 #/Monitors/TraceItem。
 * 对应 MVC 源 TraceItemController.cs / _List_Data.cshtml：
 *  - 自建 el-table 还原后端列表字段（标准列来自 GetPage 元数据，过滤掉后端自定义 url 跳转字段）
 *  - 自定义链接列（AutoPage 不渲染 Url 链接列，跳转按 MVC 源 #/... 自建）：
 *      每日监控 → #/Monitors/TraceDayStat?appId={AppId}&itemId={Id}（紧贴"操作名"列之后）
 *      审计日志 → #/Admin/Log?category=跟踪项&linkId={Id}（末列）
 *  - 批量工具栏（选中后可见）：Fix / FixDisplay 修正显示名 Action
 *      GET /Monitors/TraceItem/Fix
 *      GET /Monitors/TraceItem/FixDisplay
 *      成功 ElMessage + 刷新
 *
 * 列表用 usePageApi('Monitors','TraceItem').getList，分页 pageIndex: page-1，总条数 res.page.totalCount。
