Web_Viewer: enhance db_path configuration handling

- Improved logic for determining the database path by prioritizing the [Web_Viewer] section and falling back to the [Bot] section if necessary.
- Updated the packet stream initialization to use the resolved database path from the constructor, ensuring consistency across the application.
