26ba9ea371 [ci skip] Fix Prometheus storage alert and Grafana quota exhaustion
- Enable size-based TSDB retention (45GB) to clean up old blocks
  (including 2021-era blocks with failed compaction)
- Increase monitoring namespace quota from 64/128Gi to 80/160Gi
  CPU/memory limits to allow Grafana rolling updates

dcce738641 [ci skip] Bump inotify max_user_instances from 512 to 8192

9889728c49 [ci skip] Remove Authentik forward auth from Grafana, add admin password management
Fixes HA mobile app 403 when embedding Grafana dashboards - the webview
blocks third-party cookies needed by Authentik forward auth. Grafana
already has anonymous Viewer access enabled, so forward auth is not
needed. Also adds grafana_admin_password variable and explicit resource
limits to prevent ResourceQuota issues during rolling updates.

  and namespace-owner roles, API server OIDC flags, and audit logging
- Add self-service portal (modules/kubernetes/k8s-portal/) SvelteKit app
  with kubeconfig download and setup instructions
- Configure Alloy to collect audit logs from kube-apiserver
- Add Grafana dashboard for Kubernetes audit log visualization
- Configure Authentik OIDC provider with groups scope mapping
- Wire up k8s_users and ssh_private_key variables through module chain

039f8559c9 [ci skip] Add Grafana dashboard for Technitium DNS query logs
Add MySQL datasource and 15-panel dashboard for DNS analytics:
queries over time, response codes, top domains/clients, response
times, blocked/NxDomain domains. Enable Grafana dashboard sidecar
for auto-provisioning dashboards from ConfigMaps.

f06b3ac0e4 [ci skip] Fix .viktorbarzin.lan.viktorbarzin.lan duplicate DNS queries
Add CoreDNS catch-all block for viktorbarzin.lan.viktorbarzin.lan to
return NXDOMAIN immediately, preventing search domain expansion junk
queries from reaching Technitium. Add trailing dots to Prometheus
scrape targets (idrac, ups, ha-sofia) to bypass ndots expansion.

0eb5eb738a [ci skip] Fix Alloy OOMKill and iDRAC priority class conflict
- Alloy: bump memory limits from 64Mi/128Mi to 256Mi/768Mi — pods were
  OOMKilled at 128Mi, steady-state usage is ~400-450Mi per node
- iDRAC Redfish Exporter: add explicit priority_class_name to resolve
  conflict between Kyverno priority injection and default priority: 0

4d9b8242e8 Add tier-based resource governance via Kyverno [ci skip]
Four layers of noisy-neighbor protection using existing tier system:
- PriorityClasses (tier-0-core through tier-4-aux)
- LimitRange defaults auto-generated per namespace tier
- ResourceQuotas auto-generated per namespace tier
- PriorityClassName injection on pods via Kyverno mutate

Custom quota overrides for monitoring and crowdsec namespaces
which exceed the default tier quotas.

46ffc37dcf [ci skip] Fix all active Prometheus alerts
- meshcentral: rename port from "https" to "http" — MeshCentral serves
  plain HTTP when REVERSE_PROXY=true, but Traefik inferred HTTPS from the
  port name, causing 100% 5xx errors
- osm-routing/otp: scale to 0 — TfL GTFS data expired, OTP crash-loops
  trying to build graph with no valid transit trips
- wireguard: add prometheus.io/port=9586 annotation — without it,
  Prometheus tried scraping all container ports (51820 UDP, 80)
- travel-blog: remove stale prometheus.io annotations and dead port 9113
  — nginx-exporter sidecar was commented out but annotations remained
- dawarich: remove prometheus.io annotations — exporter env vars are
  commented out so nothing listens on port 9394
- monitoring: raise CPU temp threshold 60°C→75°C (E5-2699 v4 Tcase is
  79°C), lower registry cache threshold 50%→25%, add minimum traffic
  floor (>0.1 req/s) to 4xx/5xx rate alerts to prevent false positives
  on low-traffic services

  PrometheusStorageFull, PrometheusNotificationsFailing
- R730 Host: FanFailure (iDRAC Redfish fan health)
