The client initialized gateway connectivity from ServerWelcome, but welcome only
exposed a boolean. If a gateway disconnected before the client saw the catch-up
PeerJoined event, the later unknown PeerLeft could not be tied to the gateway
and the status could stay connected.
Carry an optional gateway peer id in ServerWelcome. The relay fills it from the
joining gateway or the existing room gateway, and the Windows client stores it
so a matching unknown PeerLeft clears gateway connectivity. The boolean remains
for wire compatibility with older welcomes that do not carry the id.
