Add an Interactive login type as a secondary login option

[PPTide]

PR for #238.

Images of the interactive login in OpenSSH and Termius:

I'm open to changes to the wording of the text xD
We should also maybe add a command in Devzat (or the login screen) where the process of creating a ssh-key is explained.

golangci-lint is broken not the formating of my code i think

@quackduck What are your thoughts? Ig this is a bigger change (allowing passkey-less login on the default :22 port aswell)

[quackduck]

can you explain the idea a bit more? also i don't understand the second screenshot. what's the feature?

[quackduck]

iirc one reason behavior differs between open and private devzat instances is because of the potential of spam and DOS. is this considered here?

edit: i may have misunderstood and possibly this is not a concern here. it's been a while since i thought about the design of devzat haha

The second screenshot is just how the passkeyless login works in termius (an ssh client that is not only in the terminal). The first screenshot is openssh.

I kinda also wanted to show that it's a different kind of login screen, that gets rendered differently by different ssh clients (ie i think putty also has a pop-up)

The passkeyless login only gets loaded when the Server is set to public. That is when before the Server on :443 would have started (which also doesn't require a passkey atm).

Now the Server at :443 is basically the same as the server on :22 and gets started if the altPort config is set.
