feat: add support for OPENAI_LIKE_API_MODELS

- Add OPENAI_LIKE_API_MODELS environment variable support
- Enable fallback model parsing when /models endpoint fails
- Support providers like Fireworks AI that don't allow /models requests
- Format: path/to/model1:limit;path/to/model2:limit;path/to/model3:limit
- Update IProviderSetting interface to include OPENAI_LIKE_API_MODELS property
- Fix all linting errors and code formatting issues
