- Introduce a new model structure for managing interface definitions and model resources, enhancing the backend's capability to handle various service integrations. - Update the Makefile to reflect changes in database seeding and resource management commands. - Remove the deprecated credentials management routes and replace them with a unified model registry API. - Modify existing routes and schemas to align with the new model structure, ensuring seamless integration with the frontend. - Enhance database seeding scripts to populate new model resources and their configurations. - Update README documentation to reflect the new architecture and usage instructions for model resources and interface definitions.
