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
