fix: remove gr.Group from outputs to avoid Gradio API schema bug

- Root cause: gr.Group as output generates schema with boolean
additionalProperties which crashes gradio_client introspection
- Removed result_group from outputs list (6 outputs instead of 7)
- Result section always visible, video/audio values passed directly
- Set ssr_mode=False in launch()
- Unpin gradio version (compatible with Python 3.13)
