-- =============================================================
-- COMPENSATING MIGRATION
-- Kompensuje: 20260302_000017_add_shoppro_orders_fetch_settings_to_integrations.sql
-- Powód: Oryginalna migracja 000017 używa prostego ALTER TABLE bez sprawdzenia
--        istnienia kolumn (nie-idempotentna). Na środowisku, gdzie kolumny
--        orders_fetch_enabled i orders_fetch_start_date już istniały (ręczne zmiany
--        lub wcześniejszy deploy), migracja 000017 zawodziła z błędem duplicate column.
--        Migracja 000039 dodaje kolumny warunkowo przez information_schema.
-- Status: Środowisko zsynchronizowane po 2026-03-08. Migracja
--         idempotentna — bezpieczna do ponownego uruchomienia.
