[#10182] Improve sanitization of processor_err_nf response

Prevent reflection of HTML in the modConnectorResponse::outputContent() method when passed via the action request parameter. This was being passed to the processor_err_nf lexicon's target parameter without proper sanitization of the data, which is returned as the JSON response's message property.

(cherry picked from commit 8c0a366e1b677d94c660ea47a98f96d0e90220e6)
