Subject: [PATCH] fix: relate provinces and municipalities in shared graph

The frontend relies on the memberships relating municipalities and province to
- automatically select the appropriate province given a municipality; and
- limit the municipality options to those in a given province.

This kind of functionality is used in both the worship and non-worship module so
the data should be readable by users with either roles. This moves the
appropriate data the `shared` graph, which can be read by all authenticated
users. Thereby fixing that that functionality was broken for users with the
worship role.
