Clob Order

CLOB-compatible order endpoint.

Accepts orders using the same schema as Polymarket’s real CLOB API (token_id + price + size), enabling one-URL-swap migration to live.

Under the hood, resolves token_id → (condition_id, outcome) from the Redis price cache, then delegates to the main trading engine.
