Refactor ProjectOverviewSerializer

[jochenklar]

This PR is a small add-on to fix-management-ui-access and fixes the problem that legacy reviewers don't see the management panels in the interview. It also refactors the serializer (and the front-end) to use RDMO3 permission format. It's a small change, I hope its ok. (ProjectOverviewSerializer will be removed eventually, I guess.)

we decided to name the permission management.view_management so I renamed it in here.

ok now I see that its actually used as a permission in ManagementView so I guess has_perm is the better idea. Maybe we should remove the can_ from the perms then:

management.view_management, management.upload_files, management.import_elements

maybe even management.upload_elements?

Then the naming is consistent and management and elements are kind of "fake" models, if you know what I mean.

from discussion, the front-end should get can_view_management, only the perm that is send from the backend needed to be fixed to management.view_management .
