fix: Toman/Rial — system uses Toman everywhere, only ZarinPal gets Rial

Core change in ZarinPalPaymentService:
- InitiatePaymentAsync: Amount (Toman) × 10 → Rial for gateway
- VerifyPaymentWithAmountAsync: Amount (Toman) × 10 → Rial for verify
- Verify result: gateway Rial ÷ 10 → Toman back to system

Also fixed:
- Package.Price doc: ریال → تومان
- Error messages in 3 handlers: ریال → تومان
- ConfigurationService descriptions: ریال → تومان (7 entries)
- Notification SMS/email: ریال → تومان
- Doc comments in 5 command files: ریال → تومان
- PaymentCallback comments: ریال → تومان
