Implement Circuit Breaker Pattern for External API Calls

[Pidoko257]

Description

Enhance the existing circuit breaker implementation to support more granular failure detection and state management across all external service integrations (providers, payment gateways, compliance services).

Acceptance Criteria

• Circuit breaker tracks per-endpoint failure rates
• Automatic state transitions (closed → open → half-open)
• Metrics exposed for monitoring
• Configurable thresholds and reset times
• Graceful degradation when circuit open

Implementation Notes

• Review current opossum configuration
• Add per-endpoint configuration
• Implement state machine for transitions
• Add Prometheus metrics export
