Felix Wolf 0095c7ee7f 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 137705bfe0 feat(matrix): add Synapse + Element Web deployment 
Personal homeserver with bridges deferred. Single host
matrix.{cluster.domain} with path-based routing: /_matrix, /_synapse,
/.well-known/matrix → Synapse; / → Element Web. Both share matrix-tls.

Stack: ananace/matrix-synapse + element-web charts, CNPG postgres
(LC_COLLATE=C), in-cluster alpine redis (no auth, replaces bitnami
subchart), mittwald-generated synapse-secrets for registration_shared/
macaroon/form_secret, custom idempotent signing-key init Job (replaces
chart's bitnami/kubectl publisher).

Sync waves:
  -3 Namespace
  -2 synapse-secrets (mittwald head-start), signing-key RBAC
  -1 signing-key Job, CNPG Cluster, redis
   0 Synapse, Element, Ingress

Synapse pod waits in extraCommands until synapse-secrets is populated,
then writes zz-overrides.yaml to override chart placeholders for the
three secret values without churning the chart-managed Secret on every
render. Resources tightened for 1-2 user scale: Synapse 256Mi/512Mi,
Postgres 64Mi/128Mi.

ArgoCD destination.namespace overridden to matrix via prototype-level
argocd overlay so both apps share the matrix ns instead of creating
unused matrix-synapse and element-web namespaces.

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.
