chrisfu 3f96f66a78 feat(mock_val): rewrite init scripts; add new service init scripts
Rewrites (updated for knoe namespace, GKE support, and current service configs):
  init_gitlab.sh, init_kong.sh, init_cnpg_backup.sh, init_monitoring.sh,
  init_garage_store.sh, init_gitea.sh, init_kdc.sh, init_openbao.sh,
  init_argocd.sh, init_certmgr.sh, init_common_services.sh, init_db_manager.sh,
  init_forgejo.sh, init_k3s_registry.sh, init_kerberos.sh, init_nginx_ingress.sh,
  init_port_forwards.sh, init_registry.sh, init_service_layer.sh

Deleted: init_cloudnative_pg.sh (superseded by init_cnpg_gke.sh)

New scripts:
  init_cnpg_gke.sh      — CNPG setup for GKE with Workload Identity
  init_knoe_auth.sh     — knoe-auth OIDC service init
  init_knoe_users.sh    — user provisioning
  init_redis.sh         — Redis init
  init_oauth2_proxy.sh / init_oauth2_proxy_prole.sh — OAuth2 proxy setup
  init_grafana_oauth.sh / init_grafana_oauth_prole.sh — Grafana OAuth wiring
  init_1password.sh     — 1Password Connect init
  init_min.sh           — minimal bootstrap

# init_grafana_oauth_prole.sh
#
# Bootstrap the Google-OAuth secret for Grafana on the prole.org k3s homelab
# cluster. Companion to the knoe.dev version (init_grafana_oauth.sh) but uses
# prole.org GCP project credentials and targets the k3s kubecontext.
#
# Creates the grafana-google-oidc Secret in the monitoring namespace, which
# kps-grafana mounts via envFromSecret to get GF_AUTH_GOOGLE_CLIENT_ID and
# GF_AUTH_GOOGLE_CLIENT_SECRET for its auth.google sign-in flow.
#
# Auth model (monitoring/kps-values-k3s.yaml):
# - Kerberos/knoe-auth users auto-login via auth.proxy (X-WEBAUTH-USER).
# - chrisfu@prole.org (and any future @prole.org Workspace user) signs in
# with the Google button on the Grafana login page.
# - chrisfu@prole.org → Admin; all other @prole.org users → Editor.
#
# Usage:
# ./etc/init_grafana_oauth_prole.sh
#
# Env vars (resolved from etc/secrets/* if not set in the shell):
# GRAFANA_GOOGLE_CLIENT_ID ← from etc/secrets/grafana-google-oidc-client-id-prole
# GRAFANA_GOOGLE_CLIENT_SECRET ← from etc/secrets/grafana-google-oidc-client-secret-prole
#
# Optional:
# K3S_KUBECONTEXT (default: $KUBECONTEXT then ambient)
# NAMESPACE (default: monitoring)
#
# Pre-reqs:
# - OAuth 2.0 Web Application client created in the prole.org GCP project:
# Authorized JS origins: https://svc.prole.org
# Authorized redirect URI: https://svc.prole.org/grafana/login/google
# Consent screen: Internal (prole.org Workspace)
# Scopes: openid, email, profile
# See deploy/gcp/gke/grafana-google-oidc-secret-prole.example.yaml for details.
# - Client ID and secret saved (chmod 0600) to:
# etc/secrets/grafana-google-oidc-client-id-prole
# etc/secrets/grafana-google-oidc-client-secret-prole
