transaction_submission_handler.rs

//! Transaction submission handler for processing submission jobs.
//!
//! Handles the submission of prepared transactions to networks:
//! - Submits transactions to appropriate networks
//! - Handles different submission commands (Submit, Cancel, Resubmit)
//! - Updates transaction status after submission
//! - Enqueues status monitoring jobs
