refactor: extract script snippets to reusable scripts

- Create modular scripts for multi-node blockchain setup
- Extract 6 core setup scripts from workflow documentation
- Add master orchestrator script for complete setup
- Replace inline code with script references in workflow
- Create comprehensive README for script documentation
- Copy scripts to aitbc for cross-node execution
- Improve maintainability and reusability of setup process

Scripts created:
- 01_preflight_setup.sh - System preparation
- 02_genesis_authority_setup.sh - Genesis node setup
- 03_follower_node_setup.sh - Follower node setup
- 04_create_wallet.sh - Wallet creation
- 05_send_transaction.sh - Transaction sending
- 06_final_verification.sh - System verification
- setup_multinode_blockchain.sh - Master orchestrator

This makes the workflow cleaner and scripts reusable
while maintaining all functionality.
