[TASK] Change merge order of new content element wizard defVals

The new content element wizard is using default values
to define on which colPos or in which language the new
element should be created.

Using TSconfig it is also possible to define custom default
values, most commonly the "CType". The user defined values
should however never overwrite the dynamically generated
values from the UI.

Therefore, the dynamic values do now always overwrite
the user defined values, like it's already done on preparing
the data map (In case "saveAndClose" is used).

Resolves: #96914
