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.

Start by locating the customer application's language-selection flow and the code that determines the system language. Reproduce the reload when selecting a language, then verify that the application detects the system language and uses it as the default without an unnecessary reload.
