feat(configurator): 'Add From Prior SO' sub-wizard for repeat orders

Task B4. New fp.add.from.so.wizard transient model: given the current
direct-order wizard + customer, lists the customer's prior confirmed
sale orders, lets the estimator tick source lines, and clones them
into fp.direct.order.line rows (part, coating, treatments, qty,
price, deadline, rush, WO group, description).

Button "+ Add From Prior SO" lives on the Lines tab of the main
wizard, visible once the customer is picked. Sub-wizard rejects
source lines that predate the new plating fields (no x_fc_part_catalog_id).

Smoke-tested on odoo-entech: copying all 3 lines of S00066 onto a
fresh wizard reproduces part/coating/qty/price correctly.
