Use the shared run_async test helper instead of bare asyncio.run in provision tests

asyncio.run() opens and tears down its own event loop per call, bypassing
the shared background loop tests/conftest.py's run_async uses to refresh
the snapshot cache after each coroutine. Switch provision.py's editor_ready
and view tests to run_async for consistency with the rest of the async
test suite.
