Implement Transaction Confirmation Mechanism in Client CLI

[AlexStroke]

Objective: Reduce test flakiness by ensuring transactions are confirmed on all peers before proceeding.

• Review the 'submit and block' function in the Python SDK: https://github.com/hyperledger/iroha-python/pull/196/files;
• Review the mechanism in the Rust SDK;
• Design a mechanism for the client CLI to wait for transaction confirmation;
• Include a configurable timeout;
• Choose a flag name (e.g., --confirm or --await);
• Integrate the mechanism into the client CLI;
• Don't broke existence client cli tests
• If you need help to update client cli tests ask @AlexStroke to do it
