- add the group_members_expanded db view
- rewrite group member queries to use the group_members_expanded view
- add the RBAC ResourceGroupMember and add it to relevant roles
- rewrite GetGroupMembersByGroupID permission checks
- make the GroupMember type contain all user fields
- fix type issues coming from replacing User with GroupMember in group member queries

* feat: Allow changing the 'group' oidc claim field
* Enable empty groups support
* fix: Delete was wiping all groups, not just the single user's groups
* Update docs
* fix: Dbfake delete group member fixed
