test(complexity): recognize the pyrange control calls by LSP strategy

cx_pyrange_exact_control counted edges with a "source":"lsp" property
that CALLS edges never carry, so every control failed and
complexity_py_module_ranges_preserve_calls_with_bounded_work reported
zero controls. Count edges whose strategy is lsp_*, the way the pyext
control and the pipeline tests recognize an LSP resolution.
