fix(fitness): resolve CodeQL and Copilot feedback comments

- Remove unused asyncio import from rp_fitness.py
- Remove unused Any import from rp_system_fitness.py
- Remove unused imports from test files (os from test_fitness.py, os and subprocess from test_system_fitness.py, _run_gpu_test_fallback from test_gpu_fitness.py)
- Add explanatory comments to empty except blocks in test_gpu_fitness_integration.py fixture cleanup
- Test assertion already uses == 6 (previously addressed)
