/**
 * Nodes/NodeFramework/Index — 节点框架管理（命令面板，自定义迁移页）
 *
 * 后端 NodeFrameworkController 继承自 NodesEntityController<Node>，[Menu(70)] 可见页，
 * 路由由 MenuTree 注册，直接访问 #/Nodes/NodeFramework。本页在其之上扩展自定义逻辑
 * （对应 MVC 源 NodeFrameworkController.cs / _List_Search.cshtml / _List_Toolbar_Batch.cshtml）：
 *  - 列表列：后端 GetPage 元数据（Node 实体字段），自建 el-table 还原
 *      （NodeFramework 控制器无自定义 Url 跳转字段，无需自建链接列，直接渲染元数据列）
 *  - 自定义 Action（命令面板，对应 _List_Toolbar_Batch 的 data-fields=keys,ver,kind）：
 *      InstallFramework   GET /Nodes/NodeFramework/InstallFramework?ver=&kind=&keys=   （安装框架）
 *      UninstallFramework GET /Nodes/NodeFramework/UninstallFramework?ver=&keys=       （卸载框架）
 *  - 自定义搜索栏（_List_Search）：类别(category) / 产品(product) / 版本(version) / 系统(osKind) 下拉 + 日期范围(dtStart/dtEnd)
 *
 * 标准列表列来自后端 GetPage 元数据的 list 字段，通过 usePageApi 对接，
 * 分页 pageIndex: page-1，总条数 res.page.totalCount。
 * 自定义 Action 写相对无前缀路径 /Nodes/NodeFramework/<Action>（request 自动拼 baseURL，勿写 /api/）。
