fix: data loss when shutting down while using typer

- Docbroker only uploads the document when the document is already saved and
  there are no further modifications.
- But when using typer once dockerbroker saves the document and tries to upload
  there are already new changes to the document. Therefore, docbroker keeps on
  saving this new changes and keeps on skiping the upload as there are new
  changes to the document; until it times out
