feat(payment): integrate Polar.sh payment provider with checkout flow

- Build PolarProvider from scratch with proper HTTP API integration
  - Add encrypted configuration loading from payment_providers table via model
  - Implement sandbox/live environment switching with proper credential handling
  - Fix product creation API structure for Polar.sh requirements
  - Add comprehensive error handling and logging throughout checkout flow
  - Fix PaymentController checkout URL handling to support Polar's checkout_url response
  - Add debug logging for troubleshooting checkout session creation
  - Support both regular and trial checkout flows for Polar payments
