- test_nextcloud_connect_persists: provider=nextcloud routes to NextcloudBackend
(not WebDAVBackend) — add storage.nextcloud_backend.validate_cloud_url patch
and use AsyncMock for asyncio.to_thread (plain return_value=True is not
awaitable, swallowed by except → False). Test now passes HTTP 201.
- test_compose_migrations: skip module when docker-compose.yml is not found at
the expected repo-root path (file is not mounted inside the backend container).
