remove unused queue.py module and refactor chain_id handling in CLI

Deleted aitbc/queue.py containing TaskQueue, JobScheduler, BackgroundTaskManager, and WorkerPool classes that were not being used in the codebase.

Refactored chain_id handling in CLI to use centralized get_chain_id utility function instead of duplicating chain_id detection logic in send_transaction, get_balance, and agent_operations functions.
