Feature: #83461 - Show fieldname next to title in debug mode

See forge#83461


If the configuration ['BE']['debug'] is enabled and the current user is an administrator, the name of a DB field is prepended to the title of each field generated by the FormEngine.


The correct name of a field is important to know for developers and integrators. Examples are setting up access permissions or configuration using TsConfig.

Instead of looking into the source code of the browser, it is now possible to display those name by enabling the debug mode for the backend.
