fix: remove double ×10 Rial conversion in ZarinPalPaymentService

Root cause: FrontOffice already converts Toman→Rial (×10) before sending
to CMS. ZarinPalPaymentService was multiplying by 10 AGAIN, causing
amounts to be 10x too large.

Example: user enters 500K Toman → FO sends 5M Rial → CMS did ×10 → 50M
Rial sent to ZarinPal → showed 5M Toman instead of 500K.

Changes:
- ZarinPalPaymentService.InitiatePaymentAsync: remove ×10 (amount already Rial)
- ZarinPalPaymentService.VerifyPaymentWithAmountAsync: remove ×10 + accept Rial
- ZarinPalPaymentService.VerifyResult.Amount: return Rial (no /10 conversion)
- VerifyMagicWalletChargeCommandHandler: remove /10 before calling Verify
- PaymentCallbackController: update comments (amount is Rial)
- Also includes: improved HTTP error logging for non-200 responses
- Also includes: production URL fix (kbs1→kbs2)
