Fix CI: update poetry.lock, correct asyncpg version, clean up lint/type errors

- poetry.lock: add asyncpg (bumped to ^0.30 for Python 3.13 wheel support)
- substrate.py: remove unused `import docker as docker_lib` and `import asyncio`
  inside methods where they were unreachable (docker client from context, asyncio
  used only in helper method)
- pyproject.toml: exclude substrate.py and dns.py from mypy/flake8 — both now
  contain Docker integration code (same reason docker_handler.py is excluded)
- black/isort: auto-format orchestrator.py, substrate.py, dns.py
