Add Title to the DB when uploading a file.

Summary
When a user uploads a document via the [UploadFile](https://balancertestsite.com/UploadFile) page, the backend should automatically extract the document title (if available) and populate the title field in the database. Currently, this field is being saved as null.

Current Behavior

- Uploaded files are saved successfully.
- The title column in the database remains null.

Expected Behavior

- Upon file upload, the server should:

1. Parse the document.
2. Attempt to extract a meaningful title (e.g., from the PDF metadata, first page header, or first large/bold line).
3. Save the extracted title to the corresponding database entry.

Backend Details

Code location: server/API/views/uploadfile.py

This logic should be added during the upload process after the file has been saved and parsed.

Suggestion: Use openAI API endpoint and sent in the first 50 words of the document and ask it to extract the document title.
