Refactor error logging to use getErrorMessage utility

- Updated multiple classes to replace direct error message access with getErrorMessage function for improved error handling and consistency.
- Modified error logging in CertRequirementManager, CloudflareDomainSync, OneboxDnsManager, OneboxDockerManager, OneboxHttpServer, Onebox, OneboxRegistriesManager, and OneboxServicesManager.
- Ensured that all error messages logged provide a standardized format and improved clarity.
