Pull Request Overview

This PR separates the concerns of Keycloak admin user management from OpenCloud admin user management in the e2e test framework. It introduces a dedicated function to create Keycloak admin user objects and updates all relevant API calls to use this specific admin user instead of the generic admin user.

• Creates a new getKeycloakAdminUser() function that returns a properly structured admin user object
• Replaces all calls to getAdminUser() with getKeycloakAdminUser() in Keycloak API operations
• Refactors token management functions to work specifically with the Keycloak admin user
