Function start_with_auth_and_admin 

pub async fn start_with_auth_and_admin(
    listen_addr: &str,
    router: Arc<RequestRouter>,
    ws_broadcaster: Arc<WsBroadcaster>,
    key_store: Arc<KeyStore>,
    counters: Arc<RuntimeCounters>,
    admin_status_provider: Option<AdminStatusProvider>,
) -> Result<()>

v1.4.32+ 同 start_with_auth，但额外接 admin_status_provider。 让 /api/admin/status 能返回实时健康快照。
