feat: migrate coordinator-api routers to use centralized aitbc package utilities

- Replace logging.getLogger with aitbc.get_logger across all router files
- Migrate HTTP client usage from httpx to aitbc.AITBCHTTPClient in blockchain.py
- Add NetworkError exception handling from aitbc package
- Update blockchain status and sync status endpoints to use AITBCHTTPClient
- Add from __future__ import annotations to admin.py, client.py, governance.py
- Consistent logger initialization across 20+ router
