Increase TGUI connection lost threshold (#80304)

Increases the TGUI connection lost timeout before the manual reconnect
button is required.

The server takes more than 20 seconds to reboot and start allowing
connections for a new round. By increasing the duration TGUI will try to
automatically reconnect, players will more consistently actually
reconnect to the new round without intervention.
