第 1 阶段:虚拟实训台,项目 2、3 的示例跑通

- 实训台状态由服务器统一保存:滑块和开关设定传感器读数,推给学生程序;
  学生程序控制的灯、继电器、LED 屏回写到实训台
- 网页按教材实训台布局图绘制实训台,传感器卡片上直接调节环境
- 新控件:CheckBox、RadioButton(事件顺序与 WinForms 一致),Lamp、Alarm
- 设备类库:串口未打开时控制无效,与实物一致
- 修正:列表属性序列化时数字被转成字符串
- 示例:项目 2 任务 2–3、项目 3 任务 1–2;网址参数 ?sample= 打开指定示例
- 测试:实训台单元测试,项目 2、3 的端到端测试
