Login with custom server & preauth key

[cmueller-tp]

Hi!
This is just a hacky PoC - works but not prod ready (I'm not a Kotlin dev).

As I see it there are 2 general options to accomplish this:

1. adding another entry in the menu with another menu to enter both
2. unifying the menus with default URL and optional preauth key (kind of what I did but what I currently have does only work with both)

What do you think?

Thank you for the contribution. We will discuss this with our UX design team to decide the correct location and flow for this feature.

Let me know if the suggested flow is to your liking, I can do a quick implementation of the intended behavior, if that helps.

What do you think about logging in via a token that consists of the preauth key and a server URI optionally encoded in a QR code? That would make logging in via smartphone very convenient and seamless for users and would also come in handy for onboarding servers with just a single token (b64) that needs to be copied over to the client.
