Optimized Endpoints for Market Makers

The following endpoints are designed to reduce gas costs and improve execution for market makers:

Cancel and Place Orders: Atomically cancels existing orders and places new ones in a single Programmable Transaction Block (PTB). This avoids the gas cost of two separate transactions and eliminates the time gap where the account has no orders on the book. Ideal for refreshing order grids.

Both endpoints return a base64-encoded TransactionKind (not the transactionBytes/signingDigest pair from CCXT endpoints). You must decode the TransactionKind, wrap it in a full Transaction, sign, and submit via your Sui client.
