Policy topology: add status/conditions

Policy topology: add status/conditions

Would need some extra data for the nodes, but as I understand it this should be relatively easy to add. This would require policy-machinery work to serialize things in a JSON format instead of a DOT file.

Start by tracing the policy-machinery topology serialization mentioned in the issue, including how node data is currently emitted as DOT. Determine where status and conditions belong on each node, then verify that the topology is emitted as JSON with those fields instead of only DOT data.
