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 files or tests are identified in the issue. Start by locating the customer application's language-selection flow and the code that reloads the application after a language choice; done means the default language follows the system language without requiring a full application reload.
