This commit adds new guidelines for FastAPI and Vue.js development, emphasizing best practices for component structure, API performance, and data handling. It also introduces caching mechanisms using Redis for improved performance and updates the API structure to streamline authentication and user management. Additionally, new endpoints for categories and time entries are implemented, enhancing the overall functionality of the application.
- Added support for refresh tokens in the authentication backend, allowing users to obtain new access tokens using valid refresh tokens.
- Created a new `BearerResponseWithRefresh` model to structure responses containing both access and refresh tokens.
- Updated the `AuthenticationBackend` to handle login and logout processes with refresh token support.
- Introduced a new `/auth/jwt/refresh` endpoint to facilitate token refreshing, validating the refresh token and generating new tokens as needed.
- Modified OAuth callback logic to generate and return both access and refresh tokens upon successful authentication.
- Updated frontend API service to send the refresh token in the Authorization header for token refresh requests.
