c8b42f78df fix DB password rotation desync in 5 stacks
Vault DB engine rotates passwords weekly but 5 stacks baked passwords
at Terraform plan time, causing stale credentials until next apply.

- real-estate-crawler: add vault-database ESO, use secret_key_ref in 3 deployments
- nextcloud: switch Helm chart to existingSecret for DB password
- grafana: add vault-database ESO, use envFromSecrets in Helm values
- woodpecker: use extraSecretNamesForEnvFrom, remove plan-time data source chain
- affine: add vault-database ESO, use secret_key_ref in deployment + init container

b2d07556d5 fix: migrate woodpecker database credentials to runtime-refreshed ExternalSecret
The woodpecker server was crashing repeatedly with database authentication failures
because Vault rotates the database password every 24 hours, but the Helm release
had hardcoded the password into WOODPECKER_DATABASE_DATASOURCE at plan time.

Changes:
- Updated ExternalSecret to provide the full DATABASE_DATASOURCE URI dynamically
- Modified Helm values to use envFrom to inject the secret instead of hardcoding
- ExternalSecret refreshes every 15 minutes, automatically picking up rotated passwords
- Pod will auto-restart when secret changes (via reloader.stakater.com annotation)
- This eliminates the plan-time password snapshot that goes stale within 24h

The pod still has an unrelated image pull issue on k8s-node4 (containerd blob
corruption), but the database credentials mechanism is now correctly implemented.

50620e6047 add generic multi-user cluster onboarding system
Data-driven user onboarding: add a JSON entry to Vault KV k8s_users,
apply vault + platform + woodpecker stacks, and everything is auto-generated.

Vault stack: namespace creation, per-user Vault policies with secret isolation
via identity entities/aliases, K8s deployer roles, CI policy update.

Platform stack: domains field in k8s_users type, TLS secrets per user namespace,
user domains merged into Cloudflare DNS, user-roles ConfigMap mounted in portal.

Woodpecker stack: admin list auto-generated from k8s_users, WOODPECKER_OPEN=true.

K8s-portal: dual-track onboarding (general/namespace-owner), namespace-owner
dashboard with Vault/kubectl commands, setup script adds Vault+Terraform+Terragrunt,
contributing page with CI pipeline template, versioned image tags in CI pipeline.

New: stacks/_template/ with copyable stack template for namespace-owners.

1acf8cc4e8 migrate consuming stacks to ESO + remove k8s-dashboard static token
Phase 9: ExternalSecret migration across 26 stacks:

Fully migrated (vault data source removed, ESO delivers secrets):
- speedtest, shadowsocks, wealthfolio, plotting-book, f1-stream, tandoor
- n8n, dawarich, diun, netbox, onlyoffice, tuya-bridge
- hackmd (ESO template for DB URL), health (ESO template for DB URL)
- trading-bot (ESO template for DATABASE_URL + 7 secret env vars)
- forgejo (removed unused vault data source)

Partially migrated (vault kept for plan-time, ESO added for runtime):
- immich, linkwarden, nextcloud, paperless-ngx (jsondecode for homepage)
- claude-memory, rybbit, url, webhook_handler (plan-time in locals/jobs)
- woodpecker, openclaw, resume (plan-time in helm values/jobs/modules)

17 stacks unchanged (all plan-time: homepage annotations, configmaps,
module inputs) — vault data source works with OIDC auth.

Phase 17a: Remove k8s-dashboard static admin token secret.
Users now get tokens via: vault write kubernetes/creds/dashboard-admin

dcb465a7e5 [ci skip] Fix Woodpecker GitHub forge: add explicit GITHUB_URL to prevent Forgejo URL bleed
When both WOODPECKER_GITHUB and WOODPECKER_FORGEJO are enabled without
an explicit WOODPECKER_GITHUB_URL, the GitHub forge inherits the Forgejo
URL causing all GitHub API calls to hit forgejo.viktorbarzin.me with
GitHub OAuth credentials, resulting in 401 Unauthorized on repo add and
cron jobs. Also adds Forgejo forge variables to Terraform.

89a6e08245 [ci skip] Infrastructure hardening: security, monitoring, reliability, maintainability
Phase 1 - Critical Security:
- Netbox: move hardcoded DB/superuser passwords to variables
- MeshCentral: disable public registration, add Authentik auth
- Traefik: disable insecure API dashboard (api.insecure=false)
- Traefik: configure forwarded headers with Cloudflare trusted IPs

Phase 2 - Security Hardening:
- Add security headers middleware (HSTS, X-Frame-Options, nosniff, etc.)
- Add Kyverno pod security policies in audit mode (privileged, host
  namespaces, SYS_ADMIN, trusted registries)
- Tighten rate limiting (avg=10, burst=50)
- Add Authentik protection to grampsweb

Phase 3 - Monitoring & Alerting:
- Add critical service alerts (PostgreSQL, MySQL, Redis, Headscale,
  Authentik, Loki)
- Increase Loki retention from 7 to 30 days (720h)
- Add predictive PV filling alert (predict_linear)
- Re-enable Hackmd and Privatebin down alerts

Phase 4 - Reliability:
- Add resource requests/limits to Redis, DBaaS, Technitium, Headscale,
  Vaultwarden, Uptime Kuma
- Increase Alloy DaemonSet memory to 512Mi/1Gi

Phase 6 - Maintainability:
- Extract duplicated tiers locals to terragrunt.hcl generate block
  (removed from 67 stacks)
- Replace hardcoded NFS IP 10.0.10.15 with var.nfs_server (114
  instances across 63 files)
- Replace hardcoded Redis/PostgreSQL/MySQL/Ollama/mail host references
  with variables across ~35 stacks
- Migrate xray raw ingress resources to ingress_factory modules
