News: redaktionell eingefuegtes FAQPage-JSON als echtes Schema ausgeben

17 SEO-Artikel tragen ein rohes FAQPage-JSON-Objekt in einem
abschliessenden Absatz ihres Bodytexts - das Frontend renderte es als
sichtbaren Text, Google sah es nie als strukturierte Daten.

Neue Klasse Seo\EmbeddedJsonLd trennt solche schema.org-Bloecke aus dem
RTE-HTML (fail-safe: was nicht sauber dekodiert, bleibt stehen):
- NewsJsonRenderer: Detail-bodytext und Listen-Exzerpt ohne die Bloecke
- PageJsonLdRenderer: die dekodierten Nodes wandern in den @graph der
  Seite (FAQPage landet damit als <script type=application/ld+json> im
  Head, den das Frontend bereits injiziert)
- VitecMetaHandler: Description-Fallback aus dem Bodytext ohne JSON-Muell

Verifiziert an 3 Artikeln: @graph mit NewsArticle + FAQPage (8-9 Fragen),
kein FAQPage-Rest im Textkoerper, kein sichtbarer JSON-Absatz im HTML.
