Fix Monitor Service Error Handling-created-by-agentic

[shaykeren]

This PR addresses the critical IllegalStateException failures in the MonitorService by:

1. Adding configurable error injection for testing purposes
2. Implementing circuit breaker pattern to prevent cascading failures
3. Adding proper error handling and recovery mechanisms
4. Improving OpenTelemetry instrumentation

Changes:

• Added configuration for error injection testing
• Implemented circuit breaker pattern with failure counting and recovery
• Added better error handling with recovery attempts
• Enhanced OpenTelemetry instrumentation for better monitoring

Testing:

• The service will now gracefully handle errors
• Circuit breaker prevents cascading failures
• Error injection can be controlled via configuration
• Better observability through enhanced instrumentation

This fixes the critical failures reported in the monitoring endpoint while maintaining the ability to test error scenarios in a controlled way.
