Ordner mit genau einer Uebersichtsseite leiten auf diese (RF Gateway, AV over IP & KVM)

Nachtrag zu 1b72e65 (Vorschlag Content-Import-Session): statt /products
zeigen die Redirects der Ordner rf-gateway und av-over-ip-and-kvm samt
ihrer Alt-URL-Redirects auf /products/avedia-modular-system bzw.
/products/aligo. Migration folder_redirect_targets_20261111 (angewendet).
