将 10 个 CycleGUI 窗体/管理器从进程级 static 单例状态改为实例字段 + 实例方法， 消除本地端/Web 端共享同一可变状态的隐患（对齐 TextViewer 正例）。 每个类保留一个 private static _instance 单实例持有者；静态入口 Open()/OpenViewer() 与实例 Show() 均转发到该实例，调用方零改动、单实例“置前”行为不变。 涉及：ChargeStationManagementForm、ChargeStrategyConfigForm、CommunicationMonitorForm、 AlarmConfigManagementForm、ButtonBoxManager、DoorManager、DoorMonitor、 LoopViewer、DeliveryViewer、TrafficInterlockViewer。 构建：dotnet build StandardScene.sln --no-incremental → 0 错误，30 警告（与基线一致，无新增）。
