Felix Wolf 0b0c434694 feat(matrix): wire Synapse into monitoring stack 
- New headless Service matrix-synapse-metrics exposing port 9090
  (Synapse's /_synapse/metrics listener), labeled matrix_metrics=enabled
- VictoriaMetrics scrape job 'matrix' targets endpoints in matrix ns
  with that label + port name 'metrics'
- Grafana picks up the official Synapse dashboard from
  element-hq/synapse v1.152.0 contrib/grafana/synapse.json via URL

Felix Wolf fe51c8c1bc feat(minikube): add minikube environment with garage S3 backend 
Adds a self-contained minikube environment for local development and
testing alongside the existing production env.

env: minikube
  - cluster.domain: minikube (browser DNS routes *.minikube → minikube ip)
  - tls issuer: mkcert (CA-signed via cert-manager mkcert ClusterIssuer)
  - storageClass: standard (minikube hostpath provisioner)
  - backups disabled; storagebox disabled
  - excludes argocd, forgejo, hcloud-csi (manual kubectl apply for testing)

prototypes/garage:
  - hand-rolled S3-compatible object store (single Deployment + PVC)
  - mittwald-generated rpc_secret + admin_token (hex)
  - PostSync init Job: assigns cluster layout, ensures bucket and access
    key, writes ocis-s3-credentials cross-namespace into ocis ns
  - idempotent: skips if k8s secret already populated; otherwise rotates
    the garage key (admin API only returns secretAccessKey on create)
  - cross-ns RBAC re-pinned via zz-cross-ns-rbac-fix overlay (ns.ytt.yaml
    clobbers explicit namespace fields)

ocis:
  - new admin-user-id init Job ensures secret.user-id is a valid UUID v4
    (mittwald can't generate UUIDs; ocis-settings rejects non-UUID ids)
  - mittwald no longer manages user-id; existing prod UUIDs preserved
  - insecure flag (oidcIdpInsecure / ocisHttpApiInsecure / ocmInsecure)
    parameterized; defaults to false; minikube sets true for self-signed
    OIDC issuer URL trust

other prototypes:
  - victoria-metrics-single helm values ytt-ified (storageClassName)
  - grafana admin secret now generated by mittwald (was hand-created in
    prod; manifest is no-op there since mittwald only fills empty fields)

flake.nix: minikube + docker + postgresql added to dev shell.

Felix Wolf d048bbb2a5 feat(monitoring): Add comprehensive oCIS monitoring 
Integrates oCIS services into the monitoring stack by:
- Adding a new scrape configuration to VictoriaMetrics to collect metrics from oCIS services in the 'ocis' namespace.
- Introducing a new "ocis Overview" Grafana dashboard. This dashboard includes panels for user experience (proxy), service health, storage activity (uploads/downloads), and resource utilization, all leveraging the VictoriaMetrics datasource.

Felix Wolf 524ccc2611 fix(grafana): Use existing secret for admin credentials 
Switch to admin.existingSecret to avoid rendering the admin password
into git. The secret must be created manually in the cluster.

Felix Wolf a92c5d8dc2 feat: Add VictoriaMetrics monitoring stack 
Adds victoria-metrics-single, grafana, kube-state-metrics, and
node-exporter to the cluster. Enables metrics endpoints on traefik,
argocd, and cert-manager for scraping. Grafana available at
grafana.tr1ceracop.de with VictoriaMetrics as default datasource.
