fix: 修复多项关键 Bug，与 openclaw 上游协议对齐

- main.js: wsClient.connect 传参格式错误（完整 ws:// URL → host:port）
- ws-client.js: request() 等待重连时不处理 onReady 握手失败
- gateway.js: bind 写入非法值 'all'，改为 openclaw 合法值 'lan'
- device.rs: connect payload 从 v2 升级到 v3，补充 platform/deviceFamily
- config.rs: macOS reload_gateway 在 async fn 中用同步 Command 阻塞 tokio
- service.rs: Windows check_service_status 端口硬编码 18789，改为读配置
- extensions.rs: parse_cftunnel_status 全角冒号解析失败，添加 split_after_colon
- tauri-api.js: cachedInvoke miss 时 logRequest 被记录两次
- tauri-api.js: mock 补充 list_agents / restart_gateway
- chat.js: 附件对象冗余 data 字段（双倍内存）+ 缩进修复
- services.js: 服务操作缺少操作中 toast 反馈
