fix: 消除 Win 闪终端 + 替换慢 CLI 操作为直接进程管理

闪终端修复：
- extensions.rs: 提取 cftunnel_cmd() 助手，Windows 自动加
  CREATE_NO_WINDOW；get_cftunnel_status/action/logs 全部改用

CLI 替换：
- config.rs reload_gateway / restart_gateway: Windows/Linux 改调
  service::restart_service()，删除慢 openclaw gateway restart CLI 调用
- config.rs uninstall_gateway: Windows 改用直接 taskkill，
  Linux 改用 pkill，不再调用 openclaw gateway stop CLI
