fix(tests): resolve 3 test failures in GUI decoupling track

- conftest.py: Create workspace dir before writing files (FileNotFoundError)
- test_live_gui_integration.py: Call handler directly since start_services mocked
- test_gui2_performance.py: Fix key mismatch (gui_2.py -> sloppy.py path lookup)
