Remove packaging-related DTOs and services, add user node functionality

The commit eliminates packaging-related DTOs, services, and transformers that are no longer in use. It introduces functionality to support user node management, including repository methods, new DTOs, and a GeoApiService placeholder. Adjustments were also made to schema constraints and node transformations.
