Grant Odoo Billing (account.group_account_invoice) to group_fp_manager via
implied_ids; Quality Manager + Owner inherit it. Billing only (not Accountant);
the SO-origin workflow gate in fusion_plating_jobs is unchanged, so managers
invoice from the Sale Order's Create Invoice action. Tests assert Manager/Owner
get Billing and Shop Manager does not.
