Enh: Provides Additional APIs for Gradio / FastAPI

[flefevre]

When we click on a workflow, we have a beautifull "PAI " widget that gives us some insight on how to code it.
It could be great to have an additional tab with Gradio implementation with a basic user interface witll all input component and the same for all output components.
if implemented with FastAPI, it could also be uplaoded directly to huggingface.

An additional tab also provided a json schema example with fake data could be also a good idea.

In order to help, I have made a small proof of concept here
https://github.com/flefevre/poc-langflowgradio/blob/main/app.py

As you can see, I have linked the gradio https://huggingface.co/blog/gradio-5
With langflow
I have add your code for file upload.

I think it is manageable to add an additional tab after python, html to provide a generated code for a basic gradio interface that is linked to the workflow.

What are your suggestions?
