Adjustments:

• send currency to back-end
• using currency from fronted fetch the appropriate values from db

Let's avoid fetching another API here. Instead, we can change the API that retrieves product details to POST request. The React frontend can send the user's location (if available) to the server, and the server will handle pricing logic and return the products with the correct prices.

For example, the current API to get product details:

https://geohosting.dev.do.kartoza.com/api/products/G3W/

Let's convert this to a POST request, with the frontend adding the user's location if it exists.
