Add RemoveOldAuditCronJob to clean up outdated audit trails

- Introduced `RemoveOldAuditCronJob` class implementing `CronJobInterface` to delete old audit trails based on configured retention period.
- Added `deleteBefore` method to `AuditTrailRepository` to handle removal of records older than the specified date.
- Created `RemoveOldAuditCronJobTest` to ensure correct functionality for job execution and canRun logic.
- Updated DI configuration to include the `delete_after` parameter for audit trail retention settings.
