H-4727: Remove usage of `viewer` and `viewFromWeb` relationships

[TimDiekmann]

🌟 What is the purpose of this PR?

When the new policy engine is used, we don't need the old relationships. However, this was not done in a single PR so we have some time where both, the policies and relationships are maintained. In the case something goes wrong with the policies and we need to revert the policy PR, we still have a working permission system.
