Fix Gradio API schema TypeError in validator_gui.py

- Fixed update_file_info function to return values instead of gr.Number objects
- Fixed toggle_range_inputs to use gr.update() instead of creating new Number objects
- This resolves the 'TypeError: argument of type bool is not iterable' in HF Spaces
