test: Stage 6 comprehensive test suite - 23/23 passing

- Created tests/test_deployment_engine.py with 23 test cases
- Fixed dict/object compatibility in config_templates and deployment_engine
- Tests cover: multi-vendor connectivity, templates, validation, rollback, errors
- All tests passing with real netmiko/napalm libraries
- Ready for real device testing
