ConnectivityService class

Web 端连通性检测与网络信息采集服务 / Connectivity detection and network information service for the web platform.

浏览器无法枚举网卡（无 dart:io），因此 IP / 网关 / MAC 等字段恒为 null； 主动可达性探测改为对公共端点发起 HTTP 请求 / Browsers cannot enumerate network interfaces (no dart:io), so IP / gateway / MAC fields are always null; the reachability probe performs an HTTP request against a public endpoint instead.
