Chore: Updates typing baseline files (#14295)

* Chore: Refresh the mypy and pyrefly baselines

* Chore: Type factory calls as the model they build for mypy

factory-boy leaves Factory() unannotated, so mypy took UserFactory() to
be a factory instance rather than a User. A shared TypedModelFactory
base declares the call as returning the model for type checking only.

* Refresh again after rebase
