fix: Geräte-Marker für Systeme ohne Statusdaten anzeigen (z. B. GMA)

- `createAndSetDevices.js` angepasst, sodass Marker auch ohne `statusDistrictData` erzeugt werden.
- Problem behoben, dass Marker wie GMA trotz vorhandener Koordinaten und Sichtbarkeit nicht gezeichnet wurden.
- Sicherheitsprüfung für Statusdaten optional gemacht, um Systems ohne Messdaten darzustellen.
