fix(quick-260921-bi2): a11y - Modul-Bereich (Kategorie-Seiten, Cert-Manager)

useButtonType: alle Aktions-Buttons in Cert-Manager-Tabs (kein Formular in
diesen Dateien) erhalten type="button".

noSvgWithoutTitle: Modul-Icons neben dem Modulnamen, Leer- und Nicht-
gefunden-Zustaende neben ihrer Ueberschrift werden dekorativ
(aria-hidden="true"); die Augen-Icons im Passwortfeld sind bereits ueber das
aria-label des umschliessenden Buttons benannt.
