1007 feature request add a new gametype field to matchroom info and to its endpoints

[tickBit]

Brief description

Related issue #1007

Add a client-defined integer gameType field to matchmaking rooms and propagate it through room responses, invites, active matches, and MQTT notifications. Matchmaking queues now separate rooms by both matchType and gameType, preventing players using different game modes from being matched together.

Testing from command line

Example output:
