Wraps all IPaymentProvider HTTP calls with an opossum CircuitBreaker to prevent a slow/unavailable gateway from exhausting the connection pool. - Add PaymentProviderCircuitBreakerService (timeout 10s, 50% error threshold, 30s half-open probe interval, volumeThreshold 5) - Proxy all IPaymentProvider methods through the breaker; throw 503 ServiceUnavailableException when the circuit is OPEN - Register service in PaymentsModule (providers + exports) - Extend HealthIndicatorsService with checkPaymentProvider() and include paymentProvider in the readiness() map - Add PaymentProviderHealthController exposing GET /health/payment-provider (503/207/200 by circuit state) and GET /health/payment-provider/status - Update HealthModule to register new controller and providers - Add 21 unit tests covering CLOSED, OPEN, and HALF_OPEN states Closes #payment-circuit-breaker
