@copilot remove moke and implement must include production grade: Stripe SDK integration for payment processing
Webhook signature verification
Email/SMS notification system...

Completed all production-grade implementations (commit 66ee6bf):

Stripe SDK Integration - Full payment processing with PaymentIntent API, error handling, and transaction tracking

Webhook Signature Verification - Secure webhook validation using stripe.webhooks.constructEvent(), rejects invalid signatures

Email/SMS Notifications - Complete notification system with SendGrid/SMTP for emails, Twilio for SMS. Sends usage alerts, payment confirmations, and failure notifications

Auto-Reload Payment - Fully implemented with invoice generation, payment processing via Stripe, credits added only on successful payment

Authentication Middleware - JWT-based auth applied to all monetization routes with database validation

TypeScript Strict Mode - All strict type checking flags enabled

All mock code removed and replaced with production implementations. See PRODUCTION_READY.md for complete deployment guide.
