Closes #628

📝 Summary

• What issue does this fix?
  PdfDocx.tsx and PdfXlsx.tsx bypass ToolPageTemplate and call useFileUpload / FileUploadArea directly. They already receive previewUrl back from the hook, but never destructured it or passed it down to FileUploadArea — so the preview never rendered even though the machinery for it already existed.

• What major changes were made?
  frontend/src/pages/PdfDocx.tsx , frontend/src/pages/PdfXlsx.tsx : destructure previewUrl from useFileUpload(), pass previewUrl={previewUrl} to .

No new components, no styling changes, no backend changes , reuses the existing preview logic already present in FileUploadArea.tsx and useFileUpload.ts.
