Comparing of Safety Numbers

[decanus]

Feature Issue

There is currently no real way to tell if my chats are actually end to end encrypted. Within apps like signal and telegram, users can compare safety numbers allowing them to be sure of this.

Status should add the safety number to the contact info screen for every conversation peer that this can be compared.

User Story

As a user, I want to be able to compare safety numbers so that I can be sure my chats are end-to-end encrypted.
