contact: fan out enquiries to n8n hub (fire-and-forget)

Keeps the direct SMTP email as the reliable delivery path; when CONTACT_HUB_URL
is set, also POSTs the enquiry to the n8n webhook so the hub sends the customer
auto-reply and (later) creates CRM/task records. Best-effort with a 4s timeout,
so a slow or down hub never blocks or fails the form.
