feat: Show requesting browser nickname on the screen

[hn0pw]

Feature description

It would be very helpful to see which connected browser is requesting a code by adding the browser extension nickname to the screen.

Example:

Motivation

If there are multiple connected browser extensions it would makes to know from which one the request was sent.
In my opinion this would increase the security as for example if the device is shared with others.
