feat: integrate NVIDIA Nemotron-3 Content Safety API for Indonesian badword detection

- Added configuration options for NVIDIA Nemotron API key, model, and base URL.
- Refactored badword detection to utilize NVIDIA API, with a fallback to a local badword list.
- Updated moderation functions to handle asynchronous operations for text evidence generation.
- Removed dependency on the `indonesian-badwords` package and implemented custom detection logic.
- Enhanced tests to accommodate asynchronous behavior and validate new detection methods.
