sendWelcomeEmailJob takes IMailerService, validates the typed input (userId + email), and delegates to mailer.sendWelcome. The onAuthUserSignedUpHandler now takes IJobQueue and enqueues "marketing-pages.send-welcome-email" with the event payload. Both binders bind a RecordingMailerService at the IMailerService symbol (production placeholder until a real adapter ships) and pass mailer / queue into the wrapped factories. Dev-seed additionally queue.register()s the slug so the in-memory queue dispatches via the wrapped job; production relies on the generated Payload event-task to resolve the wrapped handler from the container.
