Replace DaemonSet with direct host API access in favor of a regular
Deployment using Service trafficDistribution: PreferClose. This provides
prefer-local routing to the nearest cozystack-api pod with fallback
to remote pods when local one is unavailable.
- Replace DaemonSet/Deployment toggle with always-Deployment
- Replace internalTrafficPolicy: Local with trafficDistribution: PreferClose
- Remove KUBERNETES_SERVICE_HOST/PORT override (use default kubernetes service)
- Replace hard nodeSelector with soft nodeAffinity for control-plane nodes
- Simplify migration hook to always clean up DaemonSet if present

Same issue as lineage-controller-webhook: DaemonSet uses hardcoded
nodeSelector with empty value, but k3s/kubeadm use value "true".
Changes:
- Add nodeSelector to cozystack-api values (default: empty for Talos)
- Update deployment template to use configurable nodeSelector
- Pass nodeSelector for both cozystack-api and lineage-controller-webhook
in isp-full-generic bundle variant

Since 0.37, many requests to the k8s API now go through a mutating
webhook (lineage-controller-webhook). Since the lineage webhook makes
multiple requests to the k8s API and, indirectly, to the Cozystack API
server, each request for, e.g., creating a secret now causes a lot of
chatter between the webhook, the k8s API, and the Cozystack API. When
this happens cross-node or, worse yet, cross-zone, this can blow up the
latency for simple requests.
This patch changes the Cozystack API to a DaemonSet targetting
controlplane nodes, configures its service for an `Local` internal
traffic policy and adds environment variables indicating that the k8s
API server is to be found at <hostIP>:6443, **not only for the Cozystack
API, but also for the lineage-controller-webhook.** This is a valid
configuration in most scenarios, including the default installation
method on top of Talos Linux in Cozystack, however, if this is not valid
in your environment, you must now set the values
`.lineageControllerWebhook.localK8sAPIEndpoint.enabled` and
`.cozystackAPI.localK8sAPIEndpoint.enabled` to `false` in the respective
system Helm releases.
```release-note
[api,lineage] Configure all chatter between the Lineage webhook, the
Cozystack API server and the Kubernetes API server to be confined to a
single controlplane node, improving k8s API latency.
