Invert TCP connection model: client listens, server connects

The XPL2 protocol specifies that the JI2 controller initiates connections
to the client, not the other way around. Xpl2Client now listens on 3 ports
via QTcpServer and accepts inbound connections; MockServer connects out
with auto-retry on the 1s KA_PING tick.

QML API: startListening/stopListening, listening+connected properties,
host property removed. Mock server gains --host CLI arg.
