switchyard 0.11.0

• Running, a page next to the boxes and the backups: one card per namespace with its workloads, pods, containers, addresses, CPU and memory (from metrics-server), live while someone looks.
• Stop and Start per namespace and per workload. Stop brings a namespace down in order (CronJobs, Deployments, StatefulSets) and remembers what ran; Start brings it back the other way round. A box in a stopped namespace refuses deploys, and its backup schedule shows "stopped with the namespace" instead of an error.
• A new ClusterRole switchyard-running: read workloads everywhere, write only the scale subresource. New installs get it from the installer; an existing one shows an Enable button on the Running page that writes it with the admin context, once.
