feat(translators): improve system instruction extraction and input handling for OpenAI and Claude responses

- Enhanced support for extracting system instructions from input arrays.
- Improved input message role and type determination logic for consistent message processing.
- Refined instruction handling logic across translator types for better compatibility.
