Refactor SIM management and Freebit service for improved error handling and type safety

- Consolidated error handling in SimManagementService and FreebititService to provide clearer logging and user feedback.
- Enhanced type safety in FreebititService by refining type definitions for API requests and responses.
- Updated various components to ensure consistent error handling and improved user experience during SIM management actions.
