Refactor Gradio app launch and update dependencies

- Replaced direct demo launch with a new _launch_app function to handle server configuration and queuing.
- Updated Gradio version from 4.44.0 to 6.0.0 in README.md and requirements.txt.
- Removed unused API name parameter in the Gradio interface setup.
