Enatega Customer Application (App Language)

Is your feature request related to a problem? Please describe.
The application is asking for a specific language to select and when the user does that, the whole application gets reloaded.

Describe the solution you'd like
the application should be able to picked the language the system is already using and make it its default language.

No file or test is identified in the issue. Start by locating the customer application's language-selection flow and how it detects the system language. Done means the app can use the system language as its default without requiring the user to select a specific language or causing an unexpected full reload.
