feat(hub): reports from public-group members, decided by an administrator

A report needs a person's account at least a day old, membership of the
public group, and fits a daily allowance per account. Past the threshold
a hash is queued and administrators are notified; blocking without
review is an instance setting, off by default. Report menu item in
public groups, Reports tab and settings in the admin panel.
