[VR-12591] Display upload status of artifacts and prevent downloading incomplete artifacts

[daniel-verta]

Review Notes

I've tried to bundle formatting changes in clean formatting-only commits. Reviewing this using commit ranges may be easier than reviewing the atomic change.

Impact and Context

Artifacts are now tracked on the backend as having completed uploads or not. This PR makes that status visible and prevents attempts to download incomplete artifacts client-side.

Risks

Testing

• [ ] Deployed the service to dev env
• [ ] Used functionality on dev env
• [ ] Added unit test(s)
• [ ] Added integration test(s)
