Description

Describe the problem to be solved

Currently, the date formats offered have a lot of North American "month first" formats and are lacking European and African and South American "day first" formats:

Especially, the often used "DD.MM.YYYY" is missing (used at least in Germany and central European countries)

It would be great to have this added. Bonus points for selecting the "correct default display" according to the selected locale in Settings.

Research direction
The issue requests adding a 'DD.MM.YYYY' date format option. Look in the localization or date picker configuration files (likely under frontend code) for where date formats are defined. Add the new format to the list. Optionally, also investigate how to set the default format based on the user's locale (see Wikipedia link for locale mapping).
