Migrate blockchain-node scripts to centralized aitbc package utilities

- Migrate scripts/blockchain_simple.py from logging to aitbc.get_logger
- Migrate hardcoded paths in blockchain_simple.py to use DATA_DIR, CONFIG_DIR, LOG_DIR
- Migrate scripts/blockchain_http_launcher.py from logging to aitbc.get_logger
- Remove logging.basicConfig() calls
