QR scanner broken. I'll cherry-pick into another PR to fix

[brenzi]

@alex-byteport I tried to fix the z-order, but it didn't work.

problem:

1. tap send
2. tap scan QR
3. QR code scanner isn't shown (it is shown "below" send overlay)

I was able to make scanoverlay visible, but when I tap "cancel on the scan overlay, the send overlay closes instead of the scan overlay (this even happens if I remove the cancel button on scanoverlay if I tap the area where the invisible button below on sendoverlay would be.

Something is messed up with z-order. May I ask you to fix this and test the entire flow including scanning and canceling at any point?

integrated this into #33 please work on a new branch starting on top of #33 until we fix the z-order issue

@alextantumpay and please run prettier . --write before commits (or as separate commits if you like) to clean up formatting
