fix(fusion_plating_configurator): Express Order customers default customer_rank=1

Customers created from the Express Order / quote-configurator / part-catalog
pickers now default customer_rank=1, so they stay visible in those pickers and
the Customers menu (were landing at rank 0 and disappearing). The field context
is a real dict, not a string — Odoo 19 web_read does with_context(**context),
which throws TypeError on a str and broke the form.
