Telegram authentication requires you to open a chat on the phone.
It's convenient to have a QR code for the case when you want to
log in on the computer but have Telegram only on your phone
and would be able to scan the QR instead of copy-pasting the link
from the computer to the phone any other way.
Originally we thought of generating QR on the client but found
backend-generated QR a better alternative because we avoid adding
one more JavaScript dependency to the frontend that way.
