fix: populate org home sidebar with members, teams, and public member status (#183)

The org home page template expects .Members, .NumMembers, .Teams,
.IsOrganizationMember, .IsOrganizationOwner, and .IsPublicMember
but the handler only set OrgOverviewMembers and OrgOverviewTeams
(different key names). The sidebar rendered empty because the
template variables were undefined.

Fixed by adding all required data bindings and capturing the
membersIsPublic map (previously discarded) as a callable function.

Closes #183
