New translations validators.en.xlf (English)

* Implementiere bevorzugte Sprachauswahl und Datenquellen-Synonyme

Die Spracheinstellungen/System-Settings wurden um die Möglichkeit ergänzt, bevorzugte Sprachen für die Dropdown-Menüs festzulegen. Zudem wurde ein Datenquellen-Synonymsystem implementiert, um benutzerfreundlichere Bezeichnungen anzuzeigen und zu personalisieren.

* Anpassung aus Analyse

* Entferne alten JSON-basierten Datenquellen-Synonym-Handler

Die Verwaltung der Datenquellen-Synonyme wurde überarbeitet, um ein flexibleres und strukturiertes Konzept zu ermöglichen. Der bestehende JSON-basierte Ansatz wurde durch eine neue Service-basierte Architektur ersetzt, die eine bessere Handhabung und Erweiterbarkeit erlaubt.

* Ermögliche Rückgabe aller möglichen Sprachoptionen in Verbindung mit den vom Nutzer freigeschalteten.

* Removed unnecessary service definition

The tag is applied via autoconfiguration

* Use default translations for the NotBlank constraint

* Started refactoring ElementTypeNameGenerator

* Made ElementTypeNameGenerator class readonly

* Modified form to work properly with new datastructure

* Made the form more beautiful and space saving

* Made synonym form even more space saving

* Allow to define overrides for any element label there is

* Use defined synonyms in ElementTypeNameGenerator

* Use ElementTypeNameGenerator where possible

* Register synonyms for element types as global translation parameters

* Revert changes done to permission layout

* Use new synonym system for admin page titles

* Removed now unnecessary services

* Reworked settings name and translation

* Renamed all files to Synonyms

* Removed unnecessary translations

* Removed unnecessary translations

* Fixed duplicate check

* Renamed synoynms translations

* Use our synonyms for permission translations

* Fixed phpstan issue

* Added tests
