/**
 * Ticket auto-close warning email template (2026-06-10).
 *
 * Adds the 'Ticket Auto-Close Warning' notification subtype (Tickets
 * category) and the ticket-auto-close-warning email template sent to the
 * ticket's primary contact before an auto-close rule closes the ticket for
 * inactivity. The warn phase of the auto-close job gates delivery on this
 * subtype via sendNotificationIfEnabled.
 *
 * Upsert semantics (merge by (name, language_code)) — idempotent.
