Final-review fixes (XC_VM side). The startMonitor serve-only gate read the stream row via self::db(), which would throw on a serve-only LB (it has no MySQL — it serves from the replica); switch to StreamSource::serverRow, which reads the replica (and is loader-stubbable). Add the missing behavioral test for the gate: a serve-only loopback stream returns MONITOR_FANOUT (fails if the gate is removed). nodeServeOnly tests unchanged.
