### Description
This PR implements a queue timeout in the lobby server.
* After the time configured in `timeout` has elapsed (default: 3 minutes) since the first player joins the queue, matchmaking will start even if the queue has not reached the `players_per_game` target. Any missing slots will be filled with fake players.
* If the first queued player leaves and other players remain, the timer is recalculated so that matchmaking starts after the `timeout` duration (default: 3 minutes) from the next player’s join time. (After that, the timer continues to be adjusted in the same way whenever the head of the queue changes.)
