Operator data cleanup: permanently remove a wallet/bot and every record it produced — ledger transactions, the bot registry row, duels it took part in, calibration contributions, and any verified-signature rows tied to its transactions. Intended for scrubbing test/synthetic wallets from the public ledger and stats. Requires admin token. Irreversible.

Safeguard: a wallet with on-chain verified payments is treated as a real paying customer. Purging it is refused unless the request explicitly sets ?force=true, so an accidental purge cannot destroy real ledger history.
