Enhance OpenAI Test Script with Advanced Model Selection and Error Handling

- Added comprehensive model configuration and selection mechanism
- Implemented dynamic model handling for OpenAI and DeepSeek providers
- Enhanced error handling and retry logic for API interactions
- Expanded system analysis with more detailed XML-based response parsing
- Updated configuration loading with improved model selection and validation
- Added colored logging and more informative console output
- Integrated new test suite for API endpoints
