fix(quick-260921-bi2): a11y - Dashboard-Widgets und Portal-Startseite

useButtonType: "Widget hinzufuegen"-, Bearbeiten-Modus- und Katalog-Buttons
(kein Formular in diesen Dateien) erhalten type="button".

noSvgWithoutTitle: Widget-Icons in der Katalog-Kachel (immer neben dem
Widget-Namen) und Buttons mit bestehendem aria-label/title werden dekorativ
(aria-hidden="true"); der bislang unbeschriftete Such-Button im Such-Widget
erhaelt aria-label={t('search.searchButton')} (neuer Schluessel, siehe
vorherige i18n-Festschreibung).
