This commit adjusts the conditions in CalendarVoter and ActivityVoter security checks. Now it takes into account both STEP_DRAFT and STEP_CLOSED statuses in determining permissions. This enhancement ensures tighter control over specific actions in these two scenarios, enhancing the overall application security.
* the role CREATE is now transformed to CREATE_ACCOMPANYING_COURSE or
CREATE_PERSON when the subject is, respectively, a course or a person;
* the button at the list of activities is now labeled "create"
* the role FULL give access to both role
acTIVITY_CREATE_ACCOMPANYING_COURSE and ACTIVITY_CREATE_PERSON, but not
ACTIVITY_CREATE directly.
* check that transition can be applyied in menu;
* change organisation for activityVoter, and check for authorization in
Activity Controller
* fix label 'create' in accompanying course document
* minor fix in accompanying course document voter
* change color when course is closed and show old user, and startdate /
