Link the phishing page from the section people look in

Reported: "I cannot find that under Sicherheit on the website." Fair — the
page was linked from the site footer, from every mail footer and from under
the sign-in form, and none of those is where somebody goes when the thought
"is this really them?" occurs. They go to the section called Sicherheit.

It is now the last thing in that section, as its own card: what the page is
for, in one line, and where it leads.
