feat(emails): zweisprachige E-Mail-Templates + Notification-Texte org-relativ

- email_utils/templates.magic_link_login_email + incident_notification_email
  nehmen jetzt lang Parameter (de | en).
- routers/auth.request_magic_link zieht Sprache aus der Org des Users und
  uebergibt sie ans Template.
- agents/orchestrator._send_email_notifications_for_incident lokalisiert
  ebenfalls und gibt lang an incident_notification_email durch.
- DB-Notification-Texte (refresh_summary, new_articles) sind in der
  Pipeline org-sprach-relativ (englische Variante: "3 new articles", etc.).
  Status-Change-Notifications: Codes (confirmed/contradicted) bleiben, FE
  uebersetzt sie in Phase 6.

Phase 5 von 8 (eng_demo / Org-Sprache).
