fix: disable encrypted pdfs (#1130)

## Description

Currently if you complete a pending encrypted document, it will prevent
the document from being sealed due to the systems inability to decrypt
it.

This PR disables uploading any documents that cannot be loaded as a
temporary measure.

**Note**
This is a client side only check

## Changes Made

- Disable uploading documents that cannot be parsed
- Refactor putFile to putDocumentFile
- Add a flag as a backup incase something goes wrong
