Add PayPal, Stripe, CSV-Export; fix .env.production issue

- PayPal: Checkout-Integration via srmklive/paypal, Weiterleitung zu PayPal, Bestellung wird nach Capture automatisch auf payment_received gesetzt - Stripe: Payment Elements im Checkout, Intent-API, Zahlung direkt bestätigt - CSV-Export: Admin → Bestellungen → CSV exportieren (UTF-8 BOM für Excel) - PayPal/Stripe nur sichtbar wenn Keys in .env gesetzt - .env.example um PAYPAL_* und STRIPE_* Keys erweitert Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
