feat(wiki): Kategoriebeschreibungen, Kacheldesign und Migration

- Migrationsskript: Teaser/Content getrennt (kc_teaser id=55 → teaser,
  kc_article id=58 → content), Gemini-Summaries mit thinkingBudget=0,
  Retry-Logik für 503/429-Fehler
- Berechtigungsfehler behoben: AND active=1 aus main_contact_department-
  Abfrage entfernt (Middleware + Ajax)
- Kategoriebeschreibungen: neues description-Feld in
  knowledgecenter_category_translations, aus kc.tags befüllt
- Kacheln: Hauptebene erhält post_wiki-Klasse für einheitliches Design,
  Beschreibungstext in Grid-Ansicht, in Listenansicht ausgeblendet
- Buttons: Beitrag-erstellen nutzt --clr-mandant, alle vier Toolbar-
  Buttons auf gleiche Höhe normiert (line-height: 1 + SVG 1em)
- Platzhalterpfade für Kategorien und Beiträge korrigiert
- Zusammenfassung in Beitragsansicht angezeigt
