 * Monitors/AppMinuteStat/Index — 应用分钟级统计（自定义迁移页 + ECharts 双图表）
 *
 * MVC 源（_List_Data.cshtml + 控制器 Search）：
 *  - 隐藏页 [Menu(0,false)]，靠自定义视图兜底。
 *  - 列表列（与 MVC _List_Data 逐列一致）：
 *      编号 ID / 统计分钟 StatTime / 应用 AppName(始终显示) / 总次数 Total(链接) /
 *      错误数 Errors / 错误率 ErrorRate / 平均耗时 Cost / 最大耗时 MaxCost / 最小耗时 MinCost /
 *      创建时间 CreateTime / 更新时间 UpdateTime
 *  - 应用列始终显示（MVC 无 appId<=0 条件）；总次数链接到 traceData。
 *  - 行着色 ErrorRate 阈值（MVC danger/warning）；总计行聚合（ErrorRate/Cost/MaxCost/MinCost 均值，Total/Errors 求和）。
 *  - 图表（控制器 Search 权威）：双图
 *      图1（调用次数轴）：总次数 / 错误数(次轴,红)
 *      图2（耗时轴）：平均耗时 / 最小耗时 / 最大耗时(次轴)
 *  - 搜索（_List_Search）：appId 下拉 + 时间范围 dtStart/dtEnd(datetimerange)。
