Integration tests run against a live docker-compose stack.

They are marked with @pytest.mark.integration and skipped by default unless
the user runs `pytest -m integration` (or `-m "integration or not integration"`).

Each test connects to the host-published port of the service so we do not
require pytest to run inside docker.
