Scooby HuskyandClaude Opus 4.6 5163403e24 Scale down non-critical replicas for homelab resource savings 
Reduce replicas to 1 for workloads that don't need HA in a homelab:
- Prometheus 2→1, Alertmanager 2→1 (~4.4GB RAM saved)
- cert-manager 3→1
- GitLab: registry 2→1, kas 2→1, sidekiq 2→1, praefect 2→1,
  pgbouncer-ro 3→1
- Guacamole + guacd 2→1
- Kiali 2→1, ArgoCD server 2→1
- Kyverno background-controller 2→1
- Scylla operator 2→1
- ext-authz-proxy 2→1, netbird-cluster-router 2→1

Kept multi-replica: coredns, envoy-gateway, kyverno admission,
vault, argocd-repo-server, gitlab-webservice, istiod, rook-ceph CSI.

Scooby HuskyandClaude Opus 4.6 0c16785116 Fix Guacamole OIDC session persistence via Istio DestinationRule 
Traffic goes through Istio (not Envoy Gateway), so cookie-based
consistent hashing must be on the Istio DestinationRule. Removes
the unused Envoy Gateway BackendTrafficPolicy.

Scooby HuskyandClaude Opus 4.6 f71dbdb689 Add Envoy Gateway cookie-based session persistence for Guacamole OIDC 
Fixes OIDC nonce validation failures with 2 replicas by using a
BackendTrafficPolicy with cookie-based consistent hashing instead of
Service-level ClientIP affinity (which doesn't work behind Envoy proxy).

Scooby HuskyandClaude Opus 4.6 b9fd5a9461 Add session affinity to Guacamole service for OIDC flow 
With 2 replicas, OIDC callbacks can hit a different pod than the
one that generated the state/nonce, causing auth failures. Session
affinity ensures the same client always reaches the same pod.

Scooby HuskyandClaude Opus 4.6 e29eb9611b Make Authentik the primary login method for Guacamole 
Change EXTENSION_PRIORITY from "*,openid" to "openid,*" so
unauthenticated users are redirected to Authentik OIDC instead
of seeing the database login form.

Scooby HuskyandClaude Opus 4.6 131cbca4a6 Fix ArgoCD ServerSideDiff permanent OutOfSync diffs 
Add explicit CRD/API defaults to manifests that were causing ArgoCD's
SSA dry-run to produce results different from live state:

- HTTPRoutes: add group, kind, weight defaults to parentRefs/backendRefs
- Kyverno ClusterPolicies: add skipBackgroundRequests, allowExistingViolations
- Tetragon TracingPolicies: add return, maxData, resolve, returnCopy defaults
- Gateway certificateRefs: add group="" default
- Guacamole Gateway: add group="" to certificateRefs

Add ignoreDifferences for resources that legitimately differ:
- Cilium cert Secrets (auto-generated, data always differs)
- Istio ValidatingWebhookConfiguration failurePolicy (istiod mutates)
- Crowdsec LAPI Secrets (randomly generated)
- ServiceMonitor/PodMonitor relabeling action defaults
- StatefulSet volumeClaimTemplates apiVersion/kind defaults

Persist argocd-cm ignoreDifferences config in ArgoCD Helm values.
