fix(test): call sync create_app directly in ansible inventory integration test

create_app is synchronous (returns Quart) and runs its own internal
asyncio.run for settings/migrations. _make_app wrapped it in asyncio.run,
which nested event loops and raised "a coroutine is required" — the other
integration tests already call create_app() directly. This test was added
in an unpushed commit, so CI never exercised it until now.
