Main changes:

Removed the validate_endpoint function
Optimized the validate_api_connection function
Simplified API connection verification
Preserved all error handling and retry logic
Improved exception handling
The integration should now correctly verify the
OpenAI API connection without false endpoint_not_available errors.
