The <template>_product_variant auto external-ID is not reliably created in this
Odoo 19 (only 5 exist on westin-v19; none for these products or product_labor_hourly),
so the rate rows' product_id refs failed at install: 'External ID not found:
..._product_variant'. Seed each product as model=product.product (the xmlid IS the
variant; name/price/uom/etc. delegate via _inherits) and reference it directly.
In-shop labour now uses a dedicated product_labour_inshop ($75) rather than reusing
product_labor_hourly, whose variant xmlid likewise does not exist. Caught on the
Westin clone install.
