fix(web/panettone): make (who:html-mode) stick

(who:html-mode) needs to be set at macro expansion time to properly take
effect which wasn't the case before, but is ensured now by
:compile-toplevel. :load-toplevel ensures that who inside the repl will
behave the same.

Since the :html5 behavior is now actually used, we need to adjust some
of the test cases to account for the different :html5 escaping mode.
