Remove superuser property from UnicoreAuthResult.

This change deletes the superuser property from the UnicoreAuthResult class to streamline authentication data handling. The superuser role management will be handled separately or is no longer required in this context. Additional logic or methods relying on this property have been reviewed to ensure consistency.
