Replace auto-download with an interactive HTML game setup UI
No games are fetched at container start anymore. scripts/setup_server.py
is a small stdlib-only Python HTTP server, started alongside Xvnc/fluxbox/
websockify, serving an HTML page on ${SETUP_PORT} (70${DISPLAY_NUM},
published as 7099 by run.sh) that lists every *.zip found live on the SMB
share with an Installed/Install status per game. Clicking Install
downloads and extracts just that game into ${GAMES_HOME} on demand.
Replaces the old fetch_games.sh, which unconditionally pulled every game
on first start.
