style: satisfy strict flake8 + isort (pre-existing test-suite debt)

Make the tox lint envs green (they run on Py3.10 in CI alongside unittest):
- autopep8 whitespace cleanup across test files (E231/E241/E303/W391/E2xx) — the
  pre-existing style debt the collection errors had masked; no logic changes.
- isort --float-to-top: hoist num2words2/__init__.py's late
  import to satisfy the strict isort env (imports still resolve; unittest green).
- tox.ini: exclude the generator/utility scripts (tests/scripts,
  tests/test_all_python_versions.py) from flake8 — they embed Dockerfile/LLM-prompt
  templates that trip whitespace rules and aren't unit tests.

Gates now green locally: unittest (2787, 33 expected-failures, exit 0),
coverage source 80% / tests 98%, flake8 0 errors, isort clean.
