/**
 * Custom endpoint: send a test email to a given address through whatever
 * transport is currently active (SMTP or Graph — mailAdapter reads the panel
 * setting per send, so the test exercises the REAL path a form email would
 * take). Mounted at POST /api/ipal/test-email.
 *
 * Admin-only: uses payload.sendEmail (server-side), and requires an
 * authenticated admin user — a test-send button must never be open to the
 * public (it would be an open relay / spam vector).
 *
 * Returns the adapter's own result so the panel can show exactly what happened,
 * including the transport-specific error (SMTP auth failure, Graph 401, etc.).
