/**
 * pg-real tests for 20260703190000_salary_settings_p1.sql.
 *
 * Verifies:
 *   - preferred_payment_format defaults to 'pain001' for new rows (the old
 *     'bg_lb' default from 20260508120000 is retired — banks sunset
 *     Bankgirot Lön during 2026).
 *   - 'bg_lb' remains a valid explicit choice (companies with a working LB
 *     routine keep it; the UI warns instead).
 *   - salary_pay_day: default 25, CHECK 1–28.
 *   - salary_default_bank: NULL allowed, known keys allowed, unknown rejected.
