fix(controller): mark satellite ConnectionStatus=ONLINE on successful Hello

linstor-csi-node ships an init container `linstor-wait-node-online`
that polls /v1/nodes/<name> for connection_status: "ONLINE" before
letting the CSI driver register with kubelet. Hello round-tripping
already proves the node is ONLINE — emit it in the prop bag so the
piraeus DaemonSet stops looping on initContainer.

Closes the path for piraeus-operator native flip: with
externalController.url pointing at blockstor:3370, linstor-csi-node
pods now make it past Init.
