- Registrierung: Partner-Code löst Gründer-Lizenz aus (vor User-Referral geprüft)
- API: GET/POST/DELETE /api/admin/partner/codes, POST /api/admin/partner/users/{id}/grant
- API: GET /api/partner/codes/{code}/info (öffentlich, für Registrierungsvalidierung)
- API: GET /api/admin/users/search (Name-Suche für Admin-UI)
- Admin-Tab "Partner & Codes": Code anlegen, Stats, User-Status vergeben
- Registrierungsformular: Einladungscode-Feld mit Live-Validierung
