Subject: [PATCH] 301 fuer die /products-Gruppenordner auf /products
 (Entscheidung Harry 11.11.)

Die 11 Gruppenseiten des Produktbaums wurden am 10.11. im Backend zu
Ordnern (doktype 254) und antworteten seitdem 404 (Seobility-Crawl 3:
8 'technische Probleme'). Harry: Absicht -> Migration
folder_pages_redirects_20261111 (angewendet) legt 301 auf /products an
(mit und ohne Slash) und biegt aeltere Redirects, die auf einen dieser
Ordner zeigten, ebenfalls auf /products um. Inhalte auf den Ordnern
bleiben unangetastet.
