Give future test files automatic access to shared fixtures

The static_dir and static fixtures now live in conftest.py, where
pytest discovers and injects them into any test file automatically.
Helpers like ResponseCollector, make_scope, and receive stay in the
test file because they're utilities that tests instantiate directly,
not fixtures that pytest injects.
