/**
 * Redis/RedisMessageQueue/Index — Redis 消息队列（自定义迁移页）
 *
 * MVC 源 RedisMessageQueueController.cs + _List_Search.cshtml 还原：
 *  - [Menu(30,false)] 隐藏页，displayName "Redis消息队列"，路由由 MenuTree 注册，可访问 #/Redis/RedisMessageQueue
 *    （RedisNode 监控列的 队列 跳转即指向 #/Redis/RedisMessageQueue?redisId={Id}）
 *  - 标准列表列（来自后端 GetPage list 元数据，顺序即对 MVC ListFields）：
 *      编号 / Redis节点(RedisName) / 名称 / 分类 / 库 / 主题 / 类型 / 消费组 /
 *      消费者 / 总消费 / 消息数 / 最大积压 / 启用 / 最早消费 / 最后活跃 /
 *      追踪(TraceId) / 审计日志(Log) / 更新时间
 *    （WebHook、ConsumerInfo、创建系列、更新系列除 UpdateTime 已在后端 ListFields 移除）
 *    RedisName 为后端 mapField=RedisId 的扩展列（Redis节点名称）。
 *  - 独立链接列（自建，不进入自动表格列）：
 *      TraceId → 追踪：有值时显示，跳转星尘链路（降级 #/Monitors/Trace?id={TraceId}，target=_blank）
 *      Log     → 审计日志：/Admin/Log?category=Redis消息队列&linkId={Id}  (target=_frame)
 *  - 搜索（_List_Search）：节点编号(redisId) + 类别下拉(category, RedisMessageQueue.GetCategoryList()) + 日期范围(dtStart/dtEnd)
 *    后端 Search 支持 redisId/category/dtStart/dtEnd；类别下拉前端从列表聚合（同 RedisNode 做法）。
 *
 * 前端经 usePageApi + request，自定义搜索/链接均写相对无前缀路径（request 自动拼 baseURL，不要写 /api）。
