📝 Walkthrough

Walkthrough

Zano send handling now exposes native-asset balance data, checks fee affordability in the view model, prevents sending when fees are insufficient, and displays a conditional fee caution. The ZanoKit version reference was also updated.

Fee affordability state walletkit/src/main/java/io/horizontalsystems/walletkit/modules/send/zano/SendZanoViewModel.kt	Fee cautions are computed using native versus non-native balance rules and prevent sending when fees are unaffordable.
