T5 badge on room cards and the Manage tab; room_info.php for hosted rooms

room_info.php (the room card's participants, asked for every room) is answered for hosted rooms from
the hub (it was refused as naming a hosted room, which the client showed as an error), with max_users;
it and getRoomCardInfo get t5de_t5 for hosted and decorated rooms, as do the person's own rooms in
room_management_info.php.
