Why are these changes needed?

The dashboard function clusterIsRayJob (dashboard/src/utils/v2/filter.ts) relies on the legacy custom label mlp.rbx.com/component to detect RayJob-originated clusters. As a result, RayJob-created clusters that only include the official KubeRay label ray.io/originated-from-crd=RayJob are not recognized as RayJobs in the UI.

Update clusterIsRayJob to:

• Check labels["ray.io/originated-from-crd"] === "RayJob" (case-insensitive).
• Fall back to mlp.rbx.com/component for legacy environments.

Manual Testing

Launch API server and frontend server

$ go run cmd/main.go -httpPortFlag :31888 -cors-allow-origin=*

$ yarn dev

Create only RayCluster

$ k apply -f ray-operator/config/samples/ray-cluster.sample.yaml

Create RayCluster + RayJob

$ k apply -f ray-operator/config/samples/ray-job.sample.yaml

RayCluster - all

RayCluster - Cluster

RayCluster - Job
