fix(ut3server): read web admin enabled flag and port from UTWeb.ini (#5044)

UT3 stores [UWeb.WebServer] bEnabled and ListenPort in UTWeb.ini, not
UTGame.ini, so details always showed the web interface as disabled on
port 0. Parse both keys from UTWeb.ini, as kf2server does with KFWeb.ini.

Fixes #1438
