[Feature] Server url QR code for app

[rdaniel0]

I have searched the existing feature requests to make sure this is not a duplicate request.

The feature

I would like to see

Improve UX around server selection by providing more friendly completion of server-url entry

Why?

This is particularly aimed at non-tech literate users

This would reduce confusion by presenting the user with something familiar (a qr code they can scan on their camera app) that would copy or deep-link into the app to alleviate server-url entry and potentially take them straight to the login screen (a more familiar concept for most users)

Proposed criteria

1. Web/Server UI: An option somewhere to show server's url (using whatever the is in the browser's address bar?) as a QR code
   1a. Bonus: Encode url as a deeplink to the app server url entry screen
2. App: On server url screen, add an option to scan a QR code.
   2a. Bonus: Deep-link detection opens the app and fills in server url and takes user to login screen. Would need to handle logout and other edge cases.

Notes

I found this similar issue #655 also asking for qr codes for both server-url + login, but this request is specifically for just the server url
This would simplify any security concerns since we're not trying to encode authentication

Potentially duplicate discussion #6998 but this doesn't contain enough info to get started

If you agree to any of the above points, I'm happy to learn and make a PR given some direction.
I can already see there is an open (approved, not yet merged?) PR for qr codes on the web app #13128 so we can reuse that work (assuming this gets merged at some point).

Thanks for the FR! I think this is a duplicate of #6998, even if that doesn't have as much info as you've posted here - that info can be added on that request as well ;)

There's also #8766, which I think would be a basis for this feature to build on top of.

A PR would be welcome, thank you!
