[JN-1653] display/handle virus scan results

[connorlbark]

DESCRIPTION (include screenshots, and mobile screenshots for participant UX)

Not the fanciest UI but it works - will add i18n before merging.

TO TEST: (simple manual steps for confirming core behavior -- used for pre-release checks)

• Replace LocalFileStorageBackend with GCSFileStorageBackend in application.yml for admin and participant
• We can simulate an in-progress scan with an empty file (as empty files will not be picked up by the virus scanner)

touch emptyfile.txt

• Upload emptyfile.txt - you'll get an error related to it being empty, I don't think this will ever happen, so I haven't investigated this muhc
• Observe it's stuck in in-progress - look in admin view and attempt to download as participant
• You can simulate a quarantined file by manually moving the into the quarantined bucket
• Superusers can now see the external file ID in the document requests page (not visible to regular users)
• Move it over:

gsutil mv gs://juniper-participant-documents-dev-clean/<id> gs://juniper-participant-documents-dev-quarantined/<id>

• Observe how admin/participant UIs handle quarantined files
