I think i got some failed backup that was immediately shown as done. now endless loading when viewing

Steps to reproduce: (this time on TG app (build 93465) on mac sequoia 15.5

1. i tried to backup the channel from. t.me/vela_exchange. they have a pinned message.
2. i selected 6 months
3. i had already another very long running backup that was not moving
4. my newly selected backup was queued first and 3 seconds later done (for a 6 month long channel backup ?!?!? this raises eyebrows)
5. I tried viewing it and now it is in endless loading...

Now it is loading in the view. interesting to find out what happened. maybe the upload was really fast as it is mostly text, hardly images. but why did the loading not work? maybe just takes a lot longer to prepare?!? worth trying to reproduce

this feels like something that can be a fast follow - @prodalex we can try to investigate this but I'd recommend we don't block launch for it, thoughts?

I also tried backing up the same chat for 6 months, and it was really fast, mainly because it's mostly text. However, viewing it takes more time since we need to fetch, decrypt, and decode the content to display it.

We can definitely create a ticket to improve the visualization performance, but I think it's something we can tackle after the launch.

@prodalex I don't think we should block launch on this, what do you think?
