(chore) add worker queue

Deployed ClusterRole only had get/list/watch/update/patch on temporalworkers,
missing create/delete needed by reconcileTemporalWorker's cross-namespace
(sqs -> temporal) CreateOrUpdate call, and never granted apps/deployments at
all -- both required for the auto-provisioned TemporalWorker + backing
Deployment to reconcile successfully.

+## Temporal Namespace Registration — Always Automatic, Never Manual
+
+**Never manually run `temporal operator namespace create` (or the CLI/UI equivalent) for a namespace that a Queue's `temporal.io/namespace` label will reference.** `queue-operator`'s `reconcileTemporalWorker` (`internal/operator/queue_controller.go`) registers the Temporal namespace itself — idempotently, via `TemporalNamespaceRegisterer.RegisterNamespace` (`internal/operator/temporal_namespace.go`, real impl in `internal/temporal/client.go`) — before creating the `TemporalWorker` CR. This runs on every reconcile of every Queue carrying that label, so the namespace and its worker always exist together.
+
+**The only steps to bring up a new Temporal namespace + worker are:**
+1. Apply a `Queue` CR with `metadata.labels["temporal.io/namespace"] = "<namespace>"`.
+2. That's it. `queue-operator` registers the namespace, creates `TemporalWorker/worker-<namespace>` in the `temporal` namespace, and its backing Deployment.
+
+**Why this matters:** before this existed, a Queue's `temporal.io/namespace` label was trusted as-is with no verification — a typo'd or never-registered namespace silently produced a worker pod polling a namespace that doesn't exist, with no error surfaced anywhere until someone noticed workflows never executing. Manually pre-creating the namespace masks this — don't do it, let the operator own it.
+
+One `TemporalWorker` per Temporal namespace serves *all* Queues labeled with that namespace (not one worker per Queue) — see the type doc on `TemporalWorkerSpec` in `apis/kmsvc/v1/temporalworker_types.go`.
