Add field to view repo rate of any country

Cette issue n'a pas de description.

The issue title suggests adding a field to view repo rate for any country, but the body is empty. First, examine the existing codebase to understand how repo rates are currently displayed and where country-specific data is handled. Look for frontend components that manage rate display and any API calls for fetching rate data. Determine what changes are needed to the UI and data layer to support selecting and showing rates for different countries.
