"""Backfill plating defaults from fp.invoice.strategy.default → res.partner.

v3.3 merges the per-customer invoice strategy onto the partner record
itself so the new "Plating Defaults" tab is the single source of truth.
Only plain columns are migrated here (invoice_strategy + deposit %).
The legacy `fp.invoice.strategy.default` model is left in place; the
new sale.order onchange falls back to it for any partner whose record
hasn't been migrated, so downstream code keeps working mid-rollout.

property_payment_term_id is intentionally skipped — it lives in
ir_property rather than as a plain column, and the legacy onchange
fallback already reads payment_term from the strategy default record
when the partner doesn't have one set directly.
