Add explanation text to log-in page

Users are sometimes confused and trying to log into the “wrong” server.

I think part of the issue of people trying to log into a different server is also the ambiguous sign in banner text:
"Sign in to [...], or interact from your account on a different server"
Which can be read multiple ways:
1. With your account here, you can interact with other servers
2. You can sign in with credentials from another server to interact with this one.
This ambiguity is caused by the "on", which can both relate to "interact" and "account"
(Also not sure that using "Sign in" in that text makes sense, because it reads more like an onboarding text than "you're not signed in" text)

Maybe revamp those logins with “From this server” and “From another server” instead of “On this server” and “On another server”? I'm not sure how much that would help

Oh, maybe I wasn't clear enough or I'm misunderstanding you, because it doesn't sound like we're talking about the same thing. I was talking about the paragraph above the "Sign in" and "Create account" buttons shown on the landing page. I called it "sign in banner text", because the name of the variable in en.json is "sign_in_banner.text"

It sounds like you're talking about the modal shown when trying to interact with a post while visiting another server.
I think the wording on it is fine regarding ambiguity, but changing "On" to "From" sounds better imo.

@thomasmdickinson had a nice mockup of some changes that would force an active choice between "I have an account on [instance]" vs "I have an account on another Mastodon server", which might help users stop and think about it. #21821

What does "Sign in to...interact from your account on a different server" even mean? People on my instance are very confused about this, and I don't even know what it's trying to suggest. It really does read like you can log into server B with your credentials from server A.

It's two different things put together in one misleading sentence.
The first part is "Sign in to..." which tells you to sign in to interact with toots.
The second part is the "or interact from your account on a different server" which is supposed to tell you "Hey you can also interact with toots from the instance you have an account on", the whole federation thing.
