removed unused report code

What does this MR do?

Feedback from @irgendwer in orga group: At that time, the view was mainly used by the ZMG to be able to see incoming messages and to send them to the LMGs of the districts or to superordinate instances - and then to mark them as "delivered" there. Some districts with Orga people (to my recollection especially Hamburg, Cologne, Munich, Austria, at times Dresden) had also done this directly and thus relieved the ZMG a little.

But since at the moment messages can only be submitted if the district uses the corresponding GOALS function, the view is probably obsolete anyway and can be removed in my opinion.

How confident are you it won't break things if deployed?
