feat: implement comprehensive multi-provider payment processing system
- Add unified payment provider architecture with contract-based design - Implement 6 payment providers: Stripe, Lemon Squeezy, Polar, Oxapay, Crypto, Activation Keys - Create subscription management with lifecycle handling (create, cancel, pause, resume, update) - Add coupon system with usage tracking and trial extensions - Build Filament admin resources for payment providers, subscriptions, coupons, and trials - Implement payment orchestration service with provider registry and configuration management - Add comprehensive payment logging and webhook handling for all providers - Create customer analytics dashboard with revenue, churn, and lifetime value metrics - Add subscription migration service for provider switching - Include extensive test coverage for all payment functionality
