- Removed hardcoded model defaults and the MODEL_CONFIG dictionary.
- Updated get_model_config() to require an account parameter and raise clear errors if IntegrationSettings are not configured.
- Eliminated unused helper functions: get_model(), get_max_tokens(), and get_temperature().
- Improved error handling to provide specific messages for missing account or model configurations.
- Cleaned up orphan exports in __init__.py to maintain a streamlined codebase.
