 * Registry/Service/Index — 消费服务注册（自定义迁移页）
 *
 * 后端 ServiceController 继承自 EntityController<Service>，[Menu(40)] 可见页，路由由 MenuTree 注册，
 * 直接访问 #/Registry/Service。本页对接后端 GetPage 元数据（list 字段），逐列渲染对齐 MVC 呈现：
 *  - 列集合（顺序、显示名均来自后端 GetPage list 元数据，列名权威=实体 DisplayName）：
 *      Id(编号) → ProjectName(项目) → Name(名称) → DisplayName(显示名) → Category(类别)
 *      → Enable(启用) → Extranet(外网) → Singleton(单例) → UseScope(作用域)
 *      → Address(服务地址模版) → HealthCheck(健康监测)
 *      → Providers({Providers}) → Consumers({Consumers})
 *  - 独立链接列（按后端 url 字段内联渲染，不合并）：
 *      Providers → /Registry/AppService?serviceId={Id}   （MVC 源：AppService 链接列）
 *      Consumers → /Registry/AppConsume?serviceId={Id}   （MVC 源：AppConsume 链接列）
 *  - 搜索控件：名称(name) + 时间范围(dtStart/dtEnd)，对应 MVC ServiceController.Search
 *  - 空态 empty-text="暂无数据"，分页 total 来自 res.page.totalCount
 *
 * 标准列表列来自后端 GetPage 元数据的 list 字段（保留完整顺序，含独立链接列），
 * 通过 usePageApi 对接，分页 pageIndex: page-1。
