feat: pre-launch vs post-launch analysis modes

- Backend: mode field in request, adapts summary tone and email subject
- Pre-launch: "Implementieren Sie X vor Veroeffentlichung"
- Post-launch: "ACHTUNG: Maengel sind oeffentlich sichtbar, sofortige Nachbesserung"
- Frontend: Mode toggle (internes Dokument vs. Live-Website)
