[v4.49] Add groups to jobs with the serial function

You can add only groups of recipients to the iteration with the serial function. The required groups for processes with serial function must be created by the administrator and need to be added to the process configuration. However, external groups can also be created by yourself (see [v4.49] Creating external groups for the serial function).

The general groups moxisSigner and moxisApprover should not be used for jobs with the serial function.

Groups can be added to jobs with the serial function either via the address book or the search function.
