feat: add virtual environment support for Python services

- Update supervisord.conf to use venv Python executables for orchestrator and webdav-sync
- Add virtual environment setup to arty.yml setup/python-env script
- Isolate dependencies for webdav-sync, model-orchestrator, and vllm services
- Fixes dependency conflicts between services (pydantic versions)
