[Feature request] Allow users to create new contact by scanning their QR code

[rabbitholiness]

There is currently no way to just scan someone else's Bolt12 QR code and add them as a contact. I have to ask the contact to send me the offer in some other way, which adds unnecessary friction.

You can do that on Android : Settings > My contacts > +, and tap the QR code icon in the Offer input.

On iOS, you can't open the scanner from the Add contact screen, but maybe that can be fixed.
