CRDCDH-659 Poll for file validation status

[amattu2]

Overview

This PR introduces data submission polling to track the file validation status.

Tip

The validation API works, but no validation happens yet; thus you will need to manually update the data submission object to change metadataValidationStatus (sp.) or fileValidationStatus (sp) from "Validating" to another state in order to see the button re-enable.

Change Details (Specifics)

• Removed the usage of states for the Data Submission and Stats so that we can use native Apollo polling directly
• Migrated from useLazyQuery to useQuery for GET_SUBMISSION query
  • This will auto fetch the submission on component mount so that we don't need to manually initiate it
• Fixed a 508 issue with an empty button when there are no batch errors
• Fixed GenericAlert hiding under the Navbar Dropdown container (had equal z-index)

Important

This ticket can be merged, but needs to go back to On Hold while we wait for the validation service.
