Subject: [PATCH] fix: add missing UserWalletChangeLog for discount shop
 purchases and discount wallet charge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bug: when buying from discount shop, DiscountBalance was deducted from DB
but no UserWalletChangeLog was created — making it invisible in wallet history.
Same issue existed for discount wallet top-up (charge).

Fixed in 3 handlers:
- PlaceOrderCommandHandler (fully paid by discount balance path)
- CompleteOrderPaymentCommandHandler (gateway + discount balance path)
- VerifyDiscountWalletChargeCommandHandler (discount wallet charge)
