Refactor AuthService and market components for improved functionality and error handling

- Integrate LNbits API for authentication in AuthService, replacing token management with direct API calls for user data.
- Enhance login and registration processes to utilize the new API, improving user experience and error handling.
- Update market components to include detailed logging and fallback mechanisms for offline scenarios, ensuring better resilience during market data loading.
- Refactor market preloader to handle connection timeouts and provide sample data as a fallback, enhancing user experience in offline mode.
