Fix gradio 4.44.0 crashes: replace Dataframe with HTML + better patch

- Replace gr.Dataframe with gr.HTML to avoid additionalProperties schema bug
- Fix monkey-patch: delete additionalProperties key instead of replacing
with dict (which caused jinja2 unhashable type error)
- Patch get_type() to handle bool schemas
- Revert to gradio 4.44.0 (HF Spaces default)
- Remove gradio_client pin that caused conflicts
