Usability improvements for CM/Track V3

The following usability improvements for the CM/Track V3 have been made.

Duplicating cases (#665842)

The users can now clone existing cases by clicking the Duplicate button in the case header. When duplicating a case, the case fields are copied to the new case, the current user is set as a main contact, and a case is created in the same queue. This enhancement improving efficiency for users who have to create similar cases.

The Portal configurations page has been extended by the setting Show button for case duplication in the General settings section. By default, the button is available. You can set it to false to disable the duplication feature. The button text can be modified in the ticket_clone attribute of the localization.json file.

The clone script is executed when duplicating a case. It has been extended by the variable pClient with the values track or web, which can be used to implement a different behavior depending on whether the case is cloned in the Web Client or CM/Track. A script template listing the available variables has been added.

Improved news widget display (#668137)

The news widget now shows a default bell icon when the Show creation date option is disabled in the portal configuration.

The background color is determined by the color of the text class of the displayed history entry in the news case. If not set, the color defined in the Color selection field of the news widget in the portal configuration is used. The fallback color is gray.

Language selector (#668483)

A language selector has been added to the header, positioned between the dark/light mode toggle and the user menu. It is displayed whenever multiple languages are configured in the portal. The selector shows a short language code by default (e.g., EN, DE) and expands to show the full language name when opened.

By default, the language of the users' browser is selected. The user can switch the language after logging in to CM/Track.

Better display of numbers in tables (#668967)

The display of numbers and dates in tables has been improved by applying tabular number formatting, so that all digits have a consistent width.
