/**
 * Registry/AppCommand/Index — 应用命令 / 发布队列（自定义迁移页）
 *
 * 与 MVC 源（Areas/Registry/Controllers/AppCommandController.cs + 通用 List 模板）做字段/呈现级对齐：
 *  - 后端 ListFields 静态构造：
 *      RemoveField("StartTime","Expire","UpdateUserId") 移除 开始执行时间/过期时间/更新者
 *      RemoveCreateField()                               移除 创建者组扩展列（CreateUserID/CreateTime/CreateIP）
 *      AddListField("Expire", null, "Result")            在 结果 前插回 过期时间
 *      AddListField("CreateUser", "UpdateTime")          在 更新时间 前插回 创建者
 *      Command 配置独立链接 Url：/Registry/AppCommand?appId={AppId}&command={Command}
 *  - 搜索字段（通用 List 模板 + Search 参数）：应用(appId)、命令(command)、时间(dtStart/dtEnd)
 *  - 列表列与独立链接列由后端 GetPage 元数据的 list 字段驱动渲染，天然对齐 MVC 列集合/顺序/呈现。
 *
 * 后端 API：GET /api/Registry/AppCommand（GetPage / GetList）已就绪。
