Add families list, member kind filter, sidebar counters, pagination

New Families list page (parents/children columns, edit goes to the
detail view). Members list gets a member/guardian/both filter so
guardians aren't just invisible. Sidebar now shows live counts for
pending parent claims and games missing a referee, always numeric.
Member, event, team, group, news and family lists are paginated with
a shared pager partial that preserves the query string.
