+ * Kontakt-Modell — saubere Neuimplementierung auf Basis der customer-Tabelle.
+ *
+ * Unterschiede zum alten Customer-Modell:
+ *   - Global Scope schließt zusammengeführte Duplikate (merged_into_id IS NOT NULL) aus
+ *   - merged_into_id + merged_at in $fillable
+ *   - mergedInto() / mergedContacts() Beziehungen
+ *
+ * Tabellen-Name: 'customer' (wird in Phase 2 in 'contacts' umbenannt).
