Onboarding needs to be more verbose

[originalnr8]

Describe the enhancement

Onboarding from a backup is very much a black box. It loads up to ask what you want restored and then just cycles the progress bar. If it happens to work you get something but most of the time its fails to respond with anything. This needs to be addressed because sometimes it simply fails silently within a couple seconds and quite a lot of the time it finishes without actually stating its finished. Big backups take time so we having a "oh its not dead" indicator would be greatly helpful

I'm not entirely sure of a perfect fix but a reasonable start would be just some form of detail being presented.
Such as a single line of text that is the current thing being done passed back to the page for display.
Doesn't matter if its on the Observer page or the Onboarding page. Just somewhere as proof of life.
That way, we can tell its still doing something and not just sat there.

When that line has a particular signature it could also close off and say finished.

I've sadly had to do a number of restores recently and this has truly made it quite the ordeal.

Use cases

Restoring from a backup has an unreliable UI experience.
It can work but not show it has.
It can fail and not show it has.
It can partially work and not show it has.
It can take longer than thought and because of no feedback be interrupted wasting all that time.
All of this could be helped by a textbox showing its current effort.
