Implement Currency Conversion Feature

[RoyNkem]

Description:

I aim to enhance Braze app by implementing a currency conversion feature. Currently, users cannot select their preferred currency. It is important that the app dynamically converts the default currency value to the selected currency, providing a more comprehensive experience.

Goals:

Allow users to select their preferred currency from a list of options.
Implement currency conversion logic to display converted values based on the selected currency.

Additional Information:

The user's ability to choose their preferred currency will enhance their experience by displaying values in a familiar context.
Currency conversion is a valuable feature for users who deal with different currencies and want to see values in their preferred currency.
