API Management and Security Implementation

This issue focuses on the development, management, and security of APIs to ensure seamless integration between the retrieval and generation components, as well as secure access control for users and services. The work is divided into two major areas: API Development and API Gateway Implementation, with additional tasks for authentication and authorization using OAuth 2.0 and role-based access control (RBAC).

The goal is to create a robust, scalable, and secure API infrastructure that supports the application's requirements, integrates with the UI, and adheres to best practices in API management and security.

• Collaborate with the backend team to ensure the prototype is designed for seamless integration with the API tier.
• Document any specific requirements or constraints for the API integration.
