Enhance Freebit integration and improve error handling

- Added FreebitMapperService to facilitate account normalization and improve code organization.
- Updated FreebitAuthService to streamline error handling and response parsing, replacing custom exceptions with standard error messages.
- Enhanced FreebitClientService to ensure proper URL construction and improved logging for API errors.
- Refactored FreebitOperationsService to include new request types and validation, ensuring better handling of SIM operations.
- Updated FreebitOrchestratorService to utilize the new mapper for account normalization across various methods.
- Improved SIM management features in the portal, including better handling of SIM details and usage information.
- Refactored components to enhance user experience and maintainability, including updates to the ChangePlanModal and SimActions components.
