feat: implement simple AITBC wallet CLI tool

- Add simple_wallet.py with create, send, list commands
- Compatible with existing keystore structure (/var/lib/aitbc/keystore)
- Uses requests library (available in central venv)
- Supports password file authentication
- Provides JSON and table output formats
- Replaces complex CLI fallbacks with working implementation
- Update workflow to use simple wallet CLI
- Cross-node deployment to both aitbc1 and aitbc

This provides a fully functional CLI tool for wallet operations
as requested, eliminating the need for Python script fallbacks.
