TrafficTimeSpace 组件后续调整：扫描线改为蓝色加粗、沿 x 轴方向扫描；yAxis 增加底部padding（yAxisMin=-80），避免首路口柱子被 clip 裁掉；xAxis/yAxis 加 onZero=false 保证轴线画在 grid 边缘；y轴路口名称按 "-" 拆成两行显示，grid.left 加宽至 140避免左侧被挤压；三个调用页（TrunkCoordination/StatusMonitoring/SpecialSituationMonitoring）弹窗尺寸由 1000×500 改为600×900 匹配竖向布局；apiGetTrafficTimeSpace 增加 label 参数，按菜单节点 label 生成路口名前缀（${label}-路口A/B/C/D）
