Fix: declare ajaxurl global so FAQ accordion expand works

WordPress normally sets `var ajaxurl = '...'` as a standalone global.
The static export only preserved it inside the `get` object:
  var get = {"ajaxurl":"", ...}

So `ajaxurl` was an undeclared variable. Accessing it in
`EWD_UFAQ_Reveal_FAQ` threw a ReferenceError that aborted the
function before `removeClass('ewd-ufaq-hidden')` could run,
silently preventing any FAQ from expanding.

Fix: declare `var ajaxurl` at the top of ewd-ufaq.js, reading
from `get.ajaxurl` if available, otherwise defaulting to ''.
