dr-server: run Dungeon Runners Reborn headless under Wine

Browse source 
New service module on FredOS-Mediaserver that launches the friend's
Windows-only Unity server (DR_Server.exe -batchmode -nographics) in a
Win64 wine prefix. wineboot initializes the prefix on first start.
Opens auth/game/queue ports 2110, 2603-2606 (TCP+UDP).

Build files staged separately at ~/dr-server-build on the server;
sudo-move into /var/lib/dr-server/Build after the rebuild.
