tema 927d1c7dcf Refactor SIM cancellation logic and Freebit service integration for improved scheduling and error handling
- Updated SimManagementService to determine the run date for SIM cancellations, defaulting to the 1st of the next month if no date is provided.
- Modified FreebititService to align with the new cancellation request structure, utilizing the PA02-04 API for account cancellations.
- Enhanced logging to provide clearer information regarding cancellation requests and their statuses.
