Feature Request: Add PDF File Input and API Support

[sanjeevmurmu]

Description
Currently, the website and API only supports text input in the form of JSON. However, it would be beneficial to have the ability to input PDF files and send them through the API for processing.

Proposed Solution

1. PDF File Input: Add a new file input field or drag-and-drop area to allow users to upload PDF files directly into the application.

2. API Support for PDF Files: Extend the existing API endpoints to accept PDF file uploads and process them accordingly. This could involve converting the PDF to text or images, depending on the use case.

@joschan21, I would like to work on this if you approve of this feature.

It could be a nice feature, however I think there are two points:

• should pdf be "OCRed"? I think OCR is beyond the scope of this api
• we need to fix long text validation first

Thank you for the feedback.
I understand now that fixing long text validation is our priority now. I will start looking into it.
