Queue Weeztix/Mailwizz after the HTTP response and catch dispatch errors.
Jobs log Mailwizz/Weeztix API failures without rethrowing so sync driver
and terminating callbacks do not surface 500s after a successful create.
Add JS fallback for non-JSON error responses, deployment note, and a
regression test for failing Mailwizz under QUEUE_CONNECTION=sync.
