Fetch games into a volume at runtime instead of baking them into the image

927MB of the image was just t7g's two CD ISOs, which can't be meaningfully
compressed (already-compressed FMV/audio). Move the smbget/unzip step out
of the Dockerfile and into scripts/fetch_games.sh, run from server.sh on
container start: it populates GAMES_HOME on first run and skips the fetch
if games are already present. run.sh mounts a named volume so the games
survive --rm restarts instead of being re-downloaded every time. Image
drops from 1.6GB to ~690MB; first container start now needs network access
to the vlda-01 SMB share to seed the volume.
