Fix cell_magic decorator mock to handle flexible arguments

- Change decorator wrapper from (self, line, cell) to (*args, **kwargs)
- Resolves remaining TypeError in GitHub Actions test environment
- Ensures robust handling of method call variations across environments

Fixes final failing test: test_clusterfy_magic_without_ipython
All 288 tests now pass with full CI/CD compatibility.
