Preserve upload task progress when navigating in the app

Is your feature request related to a problem? Please describe.

Media file uploads take place even when you navigate away from the project space view. We need to adjust the UI to reflect this, and share data about upload progress across the app.

Describe the solution you'd like

• When navigating away from the project space after beginning an upload, I expect to see accurate updates on the status of the upload when navigating back (see additional context)
• When navigating away from the project space after beginning an upload, I should be prevented from closing the window if an upload is still in progress

Describe alternatives you've considered

We considered adding a prompt to warn users not to navigate away from the project space when an upload was in progress, but because these take place in the background, this isn't accurate / desirable.

Additional context

Currently, a file that is still uploading will render like this, when navigating away and back to the project space within the app. I think it's rendering an 'uploading' transcriptRow within the Storybook, but isn't able to access the upload progress because the uploadTasks state variable isn't being shared throughout the app
