refactor: simplify configuration handling for CMS URL

- Removed CmsServerBaseUrl utility class and updated references to directly access GwUrl from configuration.
- Adjusted frontoffice-deployment.yaml to remove CmsInternalBaseUrl environment variable.
- Updated appsettings for staging and main environments to reflect the correct CMS service URLs.
- Ensured consistent handling of GwUrl in TokenNotificationService and AddGrpcServices methods.
