/**
 * Redis/RedisNode/Index — Redis 节点列表（自定义迁移页）
 *
 * MVC 源 RedisNodeController.cs + _List_Search.cshtml 还原：
 *  - [Menu(50)] 可见页，路由由 MenuTree 注册，直接访问 #/Redis/RedisNode
 *  - 标准列：地址、端口、数据库、最大内存、已用内存、客户端、命令、连接数、状态等
 *    （WebHook、Alarm 系列、UpdateUser 系列、Remark 已在后端 ListFields 移除），由后端 GetPage 元数据提供
 *  - 自定义 url 跳转列（自建，AutoPage 不渲染）：
 *      ProjectName → /Platform/GalaxyProject?projectId={ProjectId}  (target=_frame)
 *      Monitor     → /Redis/RedisData?redisId={Id}
 *      Queue       → /Redis/RedisMessageQueue?redisId={Id}
 *      Log         → /Admin/Log?category=Redis节点&linkId={Id}       (target=_frame)
 *      Refresh     → /Redis/RedisNode/Refresh?Id={Id}                (DataAction="action")
 *  - 自定义 Action Refresh：GET /Redis/RedisNode/Refresh?id= → JsonRefresh → ElMessage + 刷新列表
 *      （清监控/刷新节点状态；[EntityAuthorize(Update)]，逐行或顶部批量刷新）
 *  - 搜索（_List_Search）：类别下拉(category, RedisNode.GetCategoryList()) + 日期范围(dtStart/dtEnd)
 *
 * 前端经 usePageApi + request，自定义 Action 写相对无前缀路径 /Redis/RedisNode/Refresh
 * （request 会自动拼 baseURL，不要写 /api/）。
