Refine registry+v1 revision phase definitions for granular resource ordering

Restructure the phase definitions to provide more granular control over
the order in which Kubernetes resources are applied during extension
installation. The previous coarse-grained phases (rbac, deploy, publish)
are replaced with finer-grained phases that better reflect resource
dependency chains and operational best practices.

Phase changes:
- Split "rbac" into "identity" (ServiceAccount), "roles" (ClusterRole,
  Role), and "bindings" (ClusterRoleBinding, RoleBinding) for explicit
  ordering of RBAC prerequisites before their bindings
- Extract "configuration" phase (Secret, ConfigMap) from "deploy" so
  config resources are available before workloads that mount them
- Extract "infrastructure" phase (Service, Issuer) from "deploy" so
  services and cert-manager issuers exist before workloads reference them
- Add "scaling" phase (VerticalPodAutoscaler) after deploy for
  autoscaling policies to target running workloads
- Add "admission" phase (ValidatingWebhookConfiguration,
  MutatingWebhookConfiguration) as the final phase so webhooks are
  registered only after their backing services are ready
- Move CRDs before roles/bindings so RBAC rules referencing custom
  resources can be validated
- Add cert-manager Certificate to "deploy" phase alongside Deployment
- Add monitoring resources (PrometheusRule, ServiceMonitor, PodMonitor)
  and OpenShift console resources to "publish" phase
- Remove explicit mappings for workload kinds that already default to
  "deploy" (DaemonSet, StatefulSet, ReplicaSet, Pod, Job, CronJob)

New phase order: namespaces → policies → identity → configuration →
storage → crds → roles → bindings → infrastructure → deploy →
scaling → publish → admission
