Investigate if we can add validation to django serializers

[drjova]

JSONSchema validation is currently implemented as an additional step in the views and endpoints within the backoffice.

Task Explore the possibility of integrating the JSONSchema validation directly into the DRF serializer, specifically for the data field.

Acceptance: If integration is feasible, JSONSchema validation should:

• Raise validation errors in the same manner as Django REST Framework (DRF) serializers.
• Maintain consistency with existing validation patterns within the project.
