Root cause: FrontOffice was converting Toman→Rial (×10) before sending to CMS,
but CMS ZarinPalService already does Toman→Rial conversion internally.
This caused double ×10 = amounts shown 10x higher in payment gateway.
Fixes:
- MagicWallet.razor.cs: remove ×10 conversion, send _chargeAmount (Toman) directly
- MagicWallet.razor: fix Max field (no /10), fix preset filter (no ×10)
- MagicWallet.razor.cs: fix FormatPrice — values from CMS are Toman, not Rial
- ChargeDiscountWallet.razor.cs: same fix — send Toman directly
- ClubMembershipContractDialog.razor: fix Price display (no /10)
- Add ChargeDiscountWallet.razor page with charge form and preset amounts
- Add ChargeDiscountWallet.razor.cs code-behind with gateway redirect logic
- Add InitiateDiscountChargeAsync client method in WalletService
- Add ChargeDiscountWallet route constant
- Add charge button link on main Wallet page
