feat: Stripe-Key-Checker, Krea AI Pattern, Scan-Progress-Tracking

- StripeKeyChecker: 2-Schritt-Check (/v1/balance + /v1/account), Live/Test-Erkennung, Balance, Account-Details
- KeyPatterns: Stripe-Patterns einkommentiert (sk_live_, sk_test_), Krea AI Pattern (UUID:Token), Mindest-Suchlänge 4
- KeyScannerService: Stripe-Check integriert, Auto-Check nach Scan entfernt (manuell separat), Progress-Tracking (Phase, Detail, Current/Total, KeysFound)
- ApiKeysEndpoint: Stripe in HandleCheck/HandleCheckAll/HandleAdopt, Progress im Status-Endpoint
- Frontend: Live-Fortschrittsanzeige mit Spinner, Phase, Query, Counter, Polling 1.5s, Krea AI in typeNames/typeIcons
