路口详情：检测器弹窗在多窗口布局下保持位置/尺寸/层级正确

  - SmartDialog 加 bringToFrontOnMousedown prop（默认 true），onRootMousedown 按开关决定是否升 z；新增
  defaultWidth/Height watcher，prop 变化即时重算 w/h
  - dialogManager.openDialog existing 分支：bringToFrontOnMousedown=false 的容器型 dialog 重入不再升 z；同时允许更新
  position/width/height/center，让父容器 rect 重算后能即时同步
  - DashboardLayout 把 bringToFrontOnMousedown 传给 SmartDialog
  - StatusMonitoring/TrunkCoordination/SpecialSituationMonitoring 的 openCrossingMultiView 配置加
  bringToFrontOnMousedown:false，避免 multi-view 容器在内部点击或重入更新时盖住其上的检测器弹窗
  - IntersectionMapVideos.handleResize 在检测器模式下重调 openDetectorDialog，让弹窗跟随 .detail-panel-right rect
  变化即时调整位置和尺寸
