fix(test): parse baddns submodule source from file (Py 3.13+ fix)

[liquidsec]

Summary

• test_baddns_max_severity_confidence failed on Python 3.13/3.14 because inspect.getsource(cls) returned a single indented attribute line (e.g. description = "..."), which ast.parse rejected with IndentationError. CPython 3.13's source-block heuristics regressed for that class.
• Each baddns submodule is exactly one class per file, so reading the whole file via inspect.getsourcefile() is equivalent and avoids the inspect.getsource heuristic entirely.
• Verified passing on 3.12, 3.13, and 3.14 locally.
