News: Canonical auf Success Story (Feld vitec_canonical_usecase), 13 Paare gesetzt

13 Pressemeldungen tragen denselben Text wie eine Success Story
(Seobility: doppelter Inhalt). Neues Feld am News-Datensatz (Tab
'VITEC SEO', Auswahl der Story); VitecMetaHandler ersetzt damit den
Canonical-Link durch /success-stories/<slug>. Die Meldung bleibt in der
Liste, Suchmaschinen werten die Story als Original. Migration
news_story_canonical_20261110 setzt die 13 Zuordnungen (angewendet).
