Phone numbers

Make the pattern easier to follow and the data more consistent by already providing land codes and flags for delight in a drop down (e.g below).

I've found this addon which looks pretty close: https://qonto.github.io/ember-phone-input/docs/usage

Do we need this to be part of Appuniversum? Don't most of our projects deal with Belgian based phone numbers? Phone number validation usually uses some rather big js libraries which we would ship to all projects, even if they don't use it. The ember-phone-input addon does seem to provide a lazy-load option though so maybe the extra weight can be ignored in apps that don't use it.

@nbittich Where does the image come from? Is that a mockup of how this should be implemented, or just an example?

@Windvis it comes from the gitbook of appuniversum => https://app.gitbook.com/o/-MP9Yduzf5xu7wIebqPG/s/-MV0jY_qXNJed_-aeOPm/research-and-ongoing/form-validation-and-errors#phone-numbers
