Broadcasts a pre-signed Solana transaction to DFlow and records the order in the platform database. Call this immediately after signing the unsignedTransaction returned by POST /kalshi/quote.

​
Notes

  • Signature must be produced on client/agent side.
  • Server does not store or process private keys.
  • Successful submit syncs order into mk_order and writes strategy log.
