Display customer currency on customer profile

🔍 Problem Statement

The Customer Profile page currently does not display the user’s currency. This lack of visibility can cause confusion when viewing financial data, payment methods, or transactions.

💡 User Story

As an admin, I want to see the currency on the Customer Profile page so that I can clearly understand the monetary values associated with the account.

🎯 Definition of Done (DoD)

A feature is done when:

1. The user’s currency is displayed on the Customer Profile page.

2. Currency is shown in a clear and visible location.

3. Currency format follows standard conventions (e.g., USD $, EUR €, etc.).

4. The displayed currency matches the user’s configured/default currency.

5. If no currency is set, a fallback state is shown (e.g., “Not set”).

6. The UI aligns with the updated design system.
