Eliminated the `RevokedToken` model and associated logic for managing token revocation. Removed unused files, related tests, and outdated dependencies in authentication modules. Simplified token decoding, user validation, and dependency injection by streamlining the flow and enhancing maintainability.
Improved the `decode_token` function to clarify and extend error handling for token validation and decoding. Enhanced error messages for invalid tokens, added checks for missing claims, and ensured clear differentiation of failure scenarios. Updated imports and added a `scope` field to token response for completeness.
Simplify database module by re-organizing engine creation, session handling, and removing redundant methods. Introduce SQLite compatibility for testing and add a utility module for test database setup and teardown. Integrate initial unit tests for user models and update dependencies for security and testing.
This commit includes configurations and boilerplate code for both frontend and backend. The frontend uses Next.js with Tailwind CSS, while the backend is built with FastAPI. Various essential files like `tsconfig.json`, `requirements.txt`, and `.gitignore` have been added to kickstart the development process.
