fix: Implement correct rack navigation in Kabelueberwachung

- Added logic to read the 'rack' query parameter from the URL using useRouter and URLSearchParams.
- Set activeRack state based on the selected rack number from the Dashboard.
- Ensured rack selection is correctly handled upon navigation.
- Maintained manual rack switching functionality with buttons.
