feat: deployment-readiness — Assets ins Package, importlib.resources, AUR PKGBUILD

Assets (default-avatar.svg, Icons) von data/ nach src/moongreet/data/
verschoben, damit sie automatisch im Wheel landen. Pfadauflösung in
greeter.py und main.py auf importlib.resources umgestellt. Dev-Fallback
in config.py entfernt — nur noch /etc/moongreet/moongreet.toml.
Beispiel-Configs für System-Deployment und AUR PKGBUILD ergänzt.
