Onboarding: Progress bar for backup uploads

[Jatoxo]

Describe the enhancement

When you upload a backup via the web interface to the device running home assistant during onboarding, there should be a stateful progress bar that shows you the current upload progress, potentially along with time estimates and upload speed.

Use cases

Since backup files are usually fairly large, and this process likely takes a long time, it would be immensely helpful to have feedback on the process. This would also show the user that something is indeed happening (as opposed to the current stateless loading bar, which you could reasonably assume is just stuck infinitely doing nothing). Currently, the only way to actually know if something is happening is external. For example, checking Task Manager for network usage.

Visual examples

Current UI with stateless loading bar. No indication of progress.

Anything else?

Unfortunately this is not a standard HTTP feature; and either wants a server side extension or to override the standard HTTP form upload functionality with AJAX handling; ie: https://codepen.io/PerfectIsShit/pen/zogMXP

Not impossible, but can be quite complex for what should hopefully be a once-a-year or less frequency activity. Touchpoints in code: https://github.com/search?q=repo%3Ahome-assistant%2Ffrontend%20ha-file-upload&type=code

How large are the backups; and are they on your local network?

I'm in this boat right now and it would be nice to have something. I have a 3.5GB backup and a 2.5Gb ethernet connection and its totally unclear if it is even working. Its been 20 minutes and I have no indication if anything at all is happening.
