docs: update multi-node workflow to use AITBC CLI tool

- Replace direct Python script calls with aitbc CLI commands
- Use 'aitbc blockchain setup' for genesis block creation
- Use 'aitbc wallet create' for wallet creation
- Use 'aitbc transaction send' for sending transactions
- Remove complex manual RPC calls and private key handling
- Simplify workflow with user-friendly CLI interface
- Add AITBC CLI tool to prerequisites
- Maintain same functionality with cleaner, more maintainable commands

This makes the workflow more accessible and reduces the chance of
errors from manual private key handling and RPC formatting.
