- Added geocoding functionality:

- Implemented address verification and geolocation in `CreateNewNode`.
  - Integrated `GeoApiService` with error handling using `GeocodingException`.
  - Updated `NodeController` for geocoding and user node creation.
  - Refactored related components and store for enhanced geolocation support.
