feat: hybrid website compliance checks (§312k BGB, §5 TMG, Art. 13 DSGVO)

- Scan public website for cancellation button, imprint, privacy link, cookie consent
- Generate follow-up questions when checks can't be verified without login
- User answers "no" → finding with legal basis is added to results
- Frontend: FollowUpQuestions component with Ja/Nein buttons
- Sidebar: "Compliance Agent" entry added under KI-Compliance
