[admin view] Filter accounts by email domains

[ChatonneLibertaire]

Pitch

Right now a moderator or an admin cannot search for all the accounts that use a particular email domain. It could be very useful to have this feature.

Motivation

Spam bots most of the time on my instance create loads of accounts using the same email domain, however blacklisting the email domain doesn't seem to automatically suspend any of the accounts already registered via this email domain. It then seems useful to be able to filter accounts by email domain to have a list of the bots

There is already an email field to filter accounts in /admin/accounts. Typing %@domain here seems to do the trick.
This is not actually documented, I'm not sure how to do it better.

ok fair enough. Maybe there could be a note somewhere in the page saying that % is a special character. I had tried with * which is the usual glob character but of course it didn't work. It seems useful to have a note somewhere on the page to notify that.
