refactor: split services/docker.py into docker/ package
Split monolithic docker.py into focused modules:
- docker/compose.py — compose generation, execute_compose_command, volume sorting
- docker/container.py — container status, IP, logs, network, port finding
- docker/config_staging.py — instance dir, env file, config file staging
- docker/tunnel.py — cloudflared tunnel lifecycle (moved from services/tunnel.py)
- docker/__init__.py — re-exports all public symbols for backward compatibility
- services/tunnel.py — thin re-export wrapper for backward compatibility
Also includes schema extraction files created in prior work:
- schemas/config/config_profile.py
- schemas/project/*.py
- schemas/system/health.py
- schemas/tool/*.py
- schemas/user/*.py
All existing imports like 'from src.services.docker import X' and
'from src.services.tunnel import X' continue to work unchanged.
Quality gates: py_compile passed, ruff passed, import test passed.
