[Bug]Locale bundle missing for 'currency'?

# 🐛 Bug

While the wallet UI does a great job of displaying spanish strings after said language is specified, the drop-down currency selector stays in english.

## To reproduce
1. Change locale from 'en' to 'es'
2. Note vast majority of strings of UI elements are displayed in spanish
=> except the currency pull down stays in english (see uploaded image)

**Code snippet to reproduce**
```rust
# Your code goes here
# Please make sure it does not require any external dependencies

## Expected Behavior

## Additional context

Add any other context about the problem here.

Start by locating the wallet UI's locale resources and the currency dropdown implementation, then trace why Spanish strings are not used there. Reproduce the issue by changing the locale from en to es and confirm that the currency options are displayed in Spanish when done.
