fix(web): App uses the Suspense API while loading the selected product (

#1877)

## Problem

The <App/> component does not wait for the information about the
selected product to be loaded.
In some corner cases, it may redirect to the software selection page
even if it is not needed.

## Solution

Use the Suspense API to be sure that the product is not selected before
redirecting to the product
selection page automatically.

## Testing
