Updated the technique for handling multiple file uploads from the user

[Heisenberg-Vader]

• What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)
  Feature Enhancement: Adds support for multiple file uploads in a single request to the /api/store_attachment endpoint.

• Why was this change needed? (You can also link to an open issue here)
  The backend previously allowed only a single document to be uploaded at a time, limiting usability for multi-file workflows. This update introduces support for multiple file uploads in one go, addressing the functionality gap discussed in
  🚀 Feature: Batch upload for attachments #2092

• Other information:

  • Changes Made:
    • Modified post() method to handle multiple files using request.files.getlist("file")
    • Implemented individual file error handling - if one file fails, others continue processing
    • Added backward compatibility for single file uploads (maintains existing API contract)
    • Each file gets its own unique attachment_id and separate Celery task for processing
  • Testing:
    • Verified multiple file uploads work on the local machine
    • Confirmed single file uploads remain unchanged
    • Tested error handling when individual files fail

I'm running into an issue when I try to execute npm run dev with these changes

4:13:00 AM [vite] (client) warning: Duplicate "multiple" attribute in JSX element
637|                  multiple
638|                  onChange={handleFileAttachment}
639|                  multiple />
   |                  ^
640|  
641|              </label>

  Plugin: vite:esbuild

When I removed the extra multiple attribute, another issue noticeable

Would you mind just double-checking your local setup to make sure the build is running smoothly?

Hey @ManishMadan2882!
Firstly, thank you for letting me know about the issue.
It appears to have been added in the code mistakenly, now it has been updated. You can try it out it again, it should now be working!

Also, there seems to have been a problem where I have removed the drag and drop functionality by mistake, I'll fix it real quick and make a commit. I apologize for such errors, its one of my first contributions.

[Heisenberg-Vader]

Hey! I have fixed the issue of missing drag and drop functionality and have added it back.

[ManishMadan2882]

Perfect, Thankyou!
