feat: 新增 Gateway 配置保存和测试消息功能

新增功能:
- OpenClaw Gateway 配置支持修改保存（地址和 Token）
- 新增测试消息通信功能，可发送测试消息验证 Gateway 连接
- 添加 URL 清理按钮（移除末尾斜杠）
- 界面显示版本号 v1.0.0-fix7

修复:
- OpenClaw WebSocket 握手协议（等待 challenge 响应）
- 关闭窗口时事件处理器访问已销毁窗口的错误
- SSL/TLS 错误诊断和提示
- 连接状态管理优化

技术改进:
- 使用 challenge-response 握手机制连接 OpenClaw Gateway
- 添加窗口销毁检查避免事件发送失败
- 改进错误日志和诊断信息
- 优化连接状态更新逻辑
