Workflow: Connect faith status of a contact to leader if they are marked as leading a group

A group record can have it be indicated that a member is leading it. This detail should be connected to the contact record so that if a contact does not the faith status set to leader, the system offers to adjust the contact record.

The same type of thing might be done when a contact has their faith status set to leader but they aren't marked as actually leading any groups.

Start by locating the group and contact record logic for marking someone as leading a group and setting faith status to leader. Define the mismatch behavior in both directions, including when the system offers to adjust the contact record; done means both inconsistencies are detected and the proposed adjustment works.
