✨ 🛍️ 🛠️ Fix/sendmodelonevent crash

[kcw-grunt]

📱 Description

Fixes a crash in the SendViewModel when toggling between fiat and LTC currencies by refactoring the currency rate lookup to use CurrencyDataGetter instead of relying on potentially stale selectedCurrency.rate. Also improves the icon tint handling in PasscodeKeypad to respect theme colors and adds shop feature strings across all supported locales. This also includes the Shop design and the localizations
