Settle all positions for an expired round using TWAP prices.
Cancels resting orders on expired instruments and optionally creates
instruments for the next round. Idempotent — settling the same
expiration twice returns success with zero counts. When
next_expiration is provided, twap_prices must include BTC, ETH,
and SOL so rollover creation stays complete and deterministic.
Admin token set via the ADMIN_TOKEN environment variable.
