refactor(openai): improve service initialization and streamline audio transcription handling

- Updated OpenaiService and related classes to enhance the initialization process by ensuring the correct order of parameters.
- Simplified audio message handling by consolidating transcription logic and improving error handling.
- Refactored the OpenaiController to utilize the new structure, ensuring better integration with the base chatbot framework.
- Enhanced logging for better traceability during audio processing and API interactions.
