-- =============================================================================
-- پچ اضطراری: wallets/transactions برای DB قدیمی بدون product_id
-- امن و idempotent — چند بار قابل اجرا؛ داده موجود را تغییر نمی‌دهد
--
-- علت خطای /customer/me:
--   Unknown column 'product_id' in 'where clause' ... from `wallets`
--
-- بعد از اجرا:
--   php artisan config:clear
--   (اختیاری) php artisan migrate  — مایگریشن همنام را هم ثبت می‌کند
