refactor: Remove Token management and integrate Redis for authentication

- Deleted the Token model and its repository, transitioning to a Redis-based token management system.
- Updated the service layer to utilize Redis for token storage, enhancing performance and scalability.
- Refactored the container to remove TokenRepository and integrate the new token service.
- Cleaned up the Dockerfile and other files by removing unnecessary whitespace and comments.
- Enhanced error handling and logging for Redis initialization and usage.
