Fission newdeploy executor does NOT apply fn.Spec.PodSpec when building
Deployment spec - it only uses env.Spec.Runtime.Container and podSpecPatch.
Fix: after updating Function CRD, also directly patch the newdeploy
Deployment via Kubernetes API using StrategicMergePatch, searching by
labels functionName/functionNamespace/executorType=newdeploy.
This ensures env vars immediately appear in the container and survive
pod scaling events (scale to 0 / scale back to 1).
