/**
* Email sending utility for the PieCed portal.
*
* Uses nodemailer with SMTP credentials from environment variables
* (populated via ExternalSecret from OpenBao at pieced/portal/smtp).
*
* Env vars (from portal-smtp K8s secret):
* SMTP_HOST — e.g. smtp.gmail.com
* SMTP_PORT — e.g. 587 (default)
* SMTP_USER — e.g. noreply@pieced.ch
* SMTP_PASS — App Password
* SMTP_FROM — e.g. "PieCed <noreply@pieced.ch>"
* ADMIN_NOTIFICATION_EMAIL — e.g. admin@pieced.ch (optional)
* SUPPORT_CONTACT_EMAIL — e.g. support@pieced.ch (optional)
* Customer-facing address for "have
* questions?" follow-ups in
* transactional emails. The from
* address itself (SMTP_USER) is
* typically a noreply mailbox, so we
* don't tell customers to "reply to
* this email" — instead we point them
* at this monitored address. If
* unset, the contact-prompt line is
* simply omitted from emails.
