fix: IPG DiscountBalance should be 2× BasePackageAmount (112M not 56M)

Both VerifyBasePackagePayment and VerifyPackagePurchase handlers were
charging DiscountBalance with 1× amount instead of 2×.
Now consistent with DayaLoan and ManualPayment handlers.

- VerifyBasePackagePaymentCommandHandler: DiscountBalance += BasePackageAmount * 2
- VerifyPackagePurchaseCommandHandler: DiscountBalance += order.Amount * 2
- Change logs updated to reflect correct 2× discount value
