test(llamaindex): make test_event_handler mypy-clean (fix CI lint)

Same pre-existing CI-lint failure (mypy runs over tests; this package has
warn_unused_ignores=true so ignores must be exact):
- FakeEvaluator evaluate_* -> (self, *args, **kwargs) -> Any so it satisfies
  EvaluatorProtocol; bare dict/list -> dict[str, Any]/list[Any].
- removed a now-unused call-arg ignore; added attr-defined ignore on the
  get_dispatcher import and an assignment ignore on the SimpleNamespace test
  context. (bedrock/vertex src errors are a local missing-extra artifact; CI
  installs --all-extras.)
