feat(status): show money-supply metric in /status

Adds economy.get_economy_stats() (single-scan total coins, house balance,
player-held coins, player count) and a "Rahavaru" field to /status, so admins
can see whether the sinks are keeping pace with minted income. Also removed a
duplicate bot_admin_check import.
