fix: 修复测试消息重复显示和详细日志输出

- 删除重复的测试消息通信模块
- 添加 openclaw-log 事件将详细日志发送到界面
- 界面监听并显示 OpenClaw 详细日志
- 日志包含：连接状态、发送请求、接收消息、响应状态、错误诊断

现在连接 OpenClaw 时会看到详细日志：
[OpenClaw] ========== 开始连接 ==========
[OpenClaw] ✅ WebSocket 连接已建立 | 就绪状态：1
[OpenClaw] 📤 发送 connect 请求...
[OpenClaw] 📥 收到消息 (长度：123 字节)
[OpenClaw] 响应：✅ 成功 / ❌ 失败
