refactor: migrate all remaining modules to use shared aitbc.logging from aitbc-core package

- Replace `import logging` with `from aitbc.logging import get_logger` across blockchain-node scripts and coordinator-api modules
- Update logger initialization from `logging.getLogger(__name__)` to `get_logger(__name__)` in 30+ files
- Add production configuration validators for API keys, HMAC secret, and JWT secret in coordinator config
- Enhance coordinator startup with comprehensive initialization logging
