Hide analytics section for event manager role

[nassabay]

Motivation

user with the role Terminplaner should not be able to see any part of the analysis section.

Proposed Solution

change user right for role Terminplaner to only see event and media library

@digitalfabrik/service-team does this also apply to the roles "author" (users who can submit pages for review) and "editor" (users who can publish pages but nothing else)?

Ok, finally we discussed this - event manager and author role should not see any analytics Editor role can see broken links and translation report but nothing else in Analytics

So editor role can stay the way it is afaict
