Remove drink_stats / total_balance / user_stats commands

All three are now superseded by the staff-only /suff/dashboard/ page
plus the year-scoped Drink and User admin views: drink_stats by the
Drink list+detail, user_stats by the User list+detail breakdown, and
total_balance by the dashboard's Refinanzierung gesamt panel.
