Subject: [PATCH] feat(backend): disable graph library

The graph library occasionally causes issues when the default graph changes substantially between versions and pydantic validation fails. See #5289 for an example.

We are not currently using the graph library, so we can disable it until we are ready to use it. It's possible that the workflow library will supersede it anyways.
