Stripe-Integration (S0–S3): Einmalzahlungen über Stripe Checkout + Notfall-Go-Live

Wegen PAYONE-Ausfall vorgezogen live geschaltet: alle Einmalzahlungen
(Shop + Salescenter) laufen über Stripe Hosted Checkout, Abos sind bis
Phase S4 eingefroren.

- Provider-Abstraktion: PaymentProvider-Enum, PaymentGatewayInterface,
  PaymentProviderManager (Settings-Schalter, provider-treu je Bestand),
  PayoneGateway als unveränderter Adapter
- StripePaymentService: Checkout Session (eine Gesamtposition, Metadata,
  success/cancel-Redirects), StripeClientWrapper (lazy, Dark Launch),
  StripeCustomerService, StripeTransactionRecorder (client_secret-Redaction)
- Webhook /stripe/webhook: Signaturprüfung, Idempotenz über
  stripe_webhook_events (Crash-Retry-Reprocessing), txaction-Prioritäten,
  Betrags-Guard, lockForUpdate-Paid-Pfad, genau eine Bestätigungsmail
- Zahlungsmethoden-Anzeige aus charge.succeeded (carddata inkl. Wallet,
  auftragsunabhängiges Backfill aus dem Event-Store)
- Checkout: Wartungsmodus mit Admin-Bypass, Abo-Freeze-Hinweis,
  Stripe-Option (Online-Zahlung) statt Zahlartenwahl, Vorkasse ausblendbar
- Abo-Freeze-Guards: Cron user:make_abo_order, Retry, Kartenupdate
- Admin-Settings-Karte Zahlungen (Provider, Wartung, Freeze, Vorkasse)
- Hotfix: 500 bei Vorkasse ohne Clearing-Daten in admin/sales/_detail
  und checkout-final (PAYONE-Ausfall)
- Doku dev/2026-07-08-stripe/ (Plan S0–S8, Konzept, IST-Analyse)
