server: fix Wss protocol error - use ws:// with transport=ssl

AsyncTcpConnection doesn't have a Wss protocol class. Workerman's Ws
protocol handles SSL via context options with transport=ssl, not via
the wss:// scheme. Changed buildHubRelayWsUrl() to always return ws://
and openHubConnection() to set transport=>'ssl' in context.
