"""Pre-migration: 19.0.12.0.0 → 19.0.13.0.0

Removes three models that are being retired in this version:
  - laundry.product.wizard       (replaced by native sale.order.line product selection)
  - laundry.product.wizard.line  (child of above)
  - laundry.whatsapp.wizard      (replaced by one-click wa.me URL action)

If these ir.model records are left in the DB while the Python classes no longer
exist, Odoo will log warnings or fail on field-level checks during upgrade.
We clean them here, before the ORM loads.
