fix(plane): apply a Task after the Workspaces it binds; end-to-end smoke Run

On the live cluster ax created the Task before its Workspace in the same apply
and the runner saw an empty AX_WORKSPACES_YAML. Tests now find rendered
documents by kind and name, not position. ops/ax/smoke-run.sh renders a
model-free repo-facts Run with the current runner digest and executes it
through the reconciler.
