This pull request includes significant updates to the authentication system, focusing on the following changes:
Refresh Token Management:
Implemented the generation and storage of refresh tokens in cookies during user registration and login.
Access Token Refresh Endpoint:
Created an endpoint to handle the refresh token, which validates the token and generates a new access token.
Error Handling Improvements:
Enhanced error handling to provide clearer messages for invalid or expired tokens.
