Sign Out keeps btn-primary and gains a log-out icon; Cancel sits beside it as a
plain button with a back arrow.
Cancel links to "/" rather than the Referer header. "/" already resolves per
tenant -- club home on a club subdomain, control panel on the base domain --
whereas Referer can be absent or point off-site, which is not something to render
as a link unchecked.
It is an anchor, not a submit, so it cannot post the form: a test asserts that
clicking it leaves the session signed in.
