feat: plakat redesign phase 4 (chat window, contact, footer, cleanup) (#77)

- AI chat moves into a window/sheet, opened from a new speech-bubble card on
  the desk; it now respects the chatbot consent and asks before sending
  anything to n8n (previously it ignored the consent)
- Contact as red poster section with big mail address and the form on a paper
  card; validation errors are finally shown inline (aria-invalid, role=alert)
- Footer as ink strip with dk0 wordmark, legal links and a button to reopen
  the privacy settings
- "About me" in the header opens the about window on the home page
- Remove the old About section and its parts (BentoChat, ActivityFeed,
  CurrentlyReading, ReadBooks), the unused ChatWidget, Projects and BentoGrid,
  their tests, wrappers, loaders, types and texts
- scripts/directus-cleanup-redesign.mjs: dry run by default, --apply archives
  hobbies, tech stack categories and old content pages and deletes four
  unused message overrides after a full JSON backup; run only after the
  redesign is live on production

+/**
+ * Räumt Directus nach dem Plakat-Redesign auf.
+ *
+ * Erst ausführen, wenn das Redesign auf production (dk0.dev) live ist — die alte
+ * Seite liest diese Einträge noch.
+ *
+ *   node scripts/directus-cleanup-redesign.mjs            # Probelauf, ändert nichts
+ *   node scripts/directus-cleanup-redesign.mjs --apply    # sichert, dann ändern
+ *
+ * Was passiert (mit --apply):
+ *   - hobbies: alle auf status "archived" (die neue Seite zeigt keine Hobby-Karten)
+ *   - tech_stack_categories: alle auf "archived" (Tech-Stack steht jetzt im Laufband)
+ *   - messages: hero.badge, hero.line1, hero.line2, about.quote.idle löschen
+ *     (überschrieben alte Hero-Texte, werden nicht mehr gelesen)
+ *   - content_pages: home-hero und home-about (beide Sprachen) auf "archived"
+ *
+ * Vorher wird alles Betroffene vollständig nach directus-backup-redesign-<zeit>.json gesichert.
+ * Archivieren lässt sich im Directus-Admin jederzeit rückgängig machen.
