GENESIS confirms the login. Wrong credentials — which GENESIS answers with HTTP 200
and an error text in Status — reject with a DestatisApiError whose isAuthError
(and loginRejected) is true; an answer that is neither an explicit success nor an
explicit failure rejects with DestatisParseError. Rejects with
DestatisValidationError for a guest client (there is nothing to check).
