[mediawiki/extensions/CentralAuth@master] Use DerivativeContext in Special:CentralAuth

@matmarex Change 479584 needs to deploy as soon as possible.

Since I had to figure out why: the issue is that viewing https://meta.wikimedia.org/wiki/Special:CentralAuth/foo, then typing in a different username and submitting the form, result in a URL like "https://meta.wikimedia.org/wiki/Special:CentralAuth/foo?target=bar" rather than "https://meta.wikimedia.org/wiki/Special:CentralAuth?target=bar" (the URL still includes the previous usename).

However, the page still works correctly. Only the URL looks silly. So while this is a bug, I don't think it is severe enough for me to be deploying it. Feel free to schedule a SWAT deployment yourself though; the next slot is on Monday (https://wikitech.wikimedia.org/wiki/Deployments).

@Volker_E Will we need to convert the legend of these both?

I have done my work on Global account information. Check it out.

@Jayprakash12345 I have too little information and insight (and time right now) to give you useful feedback. I do think though, that we should go away from normal fieldset treatment and transform such pieces to OOUI when possible. Do you have more specific questions?
