/**
 * legacy-dispatch-sync.js — PONT legacy (osTicket/MariaDB) → Dispatch Job (ERPNext).
 *
 * Tire RÉGULIÈREMENT les tickets ouverts assignés au compte « Tech Targo »
 * (staff id 3301 dans la DB legacy `gestionclient`) et crée/maj un Dispatch Job
 * dans ERPNext pour les répartir sur la grille Planification / le tableau Dispatch.
 *
 * Pourquoi 3301 : dans le legacy, le travail terrain à dispatcher est assigné au
 * compte générique « Tech Targo » (default_staff des dépts Installation/Réparation/
 * Fibre). C'est exactement « les tickets assignés à tech targo ».
 *
 * IDEMPOTENT : chaque ticket legacy porte un `legacy_ticket_id` sur le Dispatch Job.
 * On cherche avant de créer → jamais de doublon. On NE clobbe PAS le travail du
 * répartiteur : un job déjà assigné/déplacé n'est plus touché (maj de date seulement
 * tant qu'il est encore `open` + non assigné).
 *
 * Routes : GET /dispatch/legacy-sync/preview (dry-run, 0 écriture) · POST /dispatch/legacy-sync/run
 * Récurrence : startSync() (setInterval, cf. server.js), désactivable via LEGACY_DISPATCH_SYNC=off.
 *
 * Pré-requis : champ Custom Field `legacy_ticket_id` sur Dispatch Job
 * (dispatch-app/frappe-setup/setup_dispatch_custom_fields.py).
