Fix the Streamlit import error.

Current error:
ImportError: cannot import name ‘get_supported_formats’ from ‘utils.ingestion’

Please inspect:
– app_pages/upload.py
– utils/ingestion.py

Find where upload.py imports get_supported_formats from utils.ingestion.

Fix one of these ways:

Option A — Preferred:
If get_supported_formats is no longer needed, remove it from the import list in upload.py and remove any references to it.

Option B:
If the upload page still needs this helper, recreate it inside utils/ingestion.py.

Expected behavior:
– App should load without ImportError.
– Upload page should still show supported file types.
– Supported formats should match the actual ingestion logic.

Suggested helper if needed:

def get_supported_formats():
return {
“CSV”: [“.csv”],
“Excel”: [“.xlsx”, “.xls”],
“PDF”: [“.pdf”],
“Word”: [“.docx”],
“Text”: [“.txt”]
}

Also search the whole codebase for:
get_supported_formats

Update every broken import/reference so there is only one source of truth.
Run the app after fixing to confirm the upload page loads successfully.
