Chore: convert test_signals.py from TestCase to pytest style

22 near-duplicate test methods. Converts to plain pytest classes to enable
pytest.mark.parametrize, which collapses those into 9 test functions covering 23 cases,
with mocker/caplog/settings fixtures replacing unittest.mock/assertLogs/override_settings.

The role-sync scenarios (superuser/staff group sync, in various combinations)
share the same setup and assertions, so they're merged into one parametrize
table.
