feat(iam): read the Zitadel bootstrap token from .env

ZITADEL_BOOTSTRAP_TOKEN and ZITADEL_URL now live in .env and .env.example, the same shape the Authentik variables use. The line is present and empty: the PAT does not exist until the chart's setup job creates the iam-admin machine user on the first sync, so a value cannot be minted ahead of time. The provisioning script loads .env itself instead of relying on the caller to source it, and resolves the token in a fixed order: ZITADEL_BOOTSTRAP_TOKEN, then the cached file under ~/.config/zitadel, then the cluster Secret. The .env value wins so a human can paste a rotated token without touching the cluster; the cluster Secret remains the only source that always reflects a rotation. .env stays git-ignored. It already holds the live Authentik secrets, and this change does not move them. Not exercised against a live instance: the kube-apiserver on talos-cp-1 is in CrashLoopBackOff, so kubectl only works against cp-2 or cp-3 right now.
feat(iam): one script to provision Zitadel end to end

+# etcd backend maintenance: compact, defrag, disarm NOSPACE.
+#
+# Why this exists
+# ---------------
+# etcd's backend file only grows. The apiserver compacts every 5m, but
+# compaction marks superseded revisions free *inside* the file; only `defrag`
+# returns that space to the filesystem. Nothing ran defrag, so the file grew
+# until it crossed the 2 GiB quota:
+#
+#   2026-10-07  backend 2,148,843,520 B (2.1 GB) on talos-cp-1 and talos-cp-3
+#               -> etcd raised NOSPACE on those two members
+#               -> etcd rejected ALL writes cluster-wide
+#               -> kubelets could not post node status: 3 nodes NotReady
+#               -> apiserver writes returned 500, the tunnel API path 502
+#
+# The live data was tiny: 15,943 keys, 69 MB after compaction. The rest was
+# dead pages. Recovery was `compact <current-revision>` then `defrag` per
+# member then `alarm disarm`. Compaction had also stalled while the alarm was
+# up, so `dbSizeInUse` read 100% of the file - defrag alone would NOT have
+# worked. Order matters: compact first, then defrag.
+#
+# The earlier revision of this file never ran, for two independent reasons:
+#   1. it existed only on branch fix/etcd-defrag-cron; the ArgoCD application
+#      `cluster-maintenance` tracks `main` (targetRevision: main), so the
+#      cluster never had the CronJob or the Secret.
+#   2. the image was quay.io/coreos/etcd, which has NO /bin/sh (verified:
+#      `exec: "/bin/sh": no such file or directory`). Any container that runs
+#      a shell script needs an image that ships one.
+# This revision fixes both: image bitnamilegacy/etcd (ships bash + etcdctl
+# 3.6.4, matching the 3.6.11 servers) pinned by digest.
+#
+# Cadence: every 15 days. Measured growth is ~29 MB/day, so a 15-day cycle
+# peaks near 500 MB - comfortably under the 2 GiB quota. The schedule is daily
+# and the script exits unless the UTC epoch day is a multiple of 15. That gives
+# an exact 15-day interval; `*/15` in the day-of-month field does not (it fires
+# on the 1st, 16th and 31st, which puts two runs one day apart).
+#
+# Safety
+# ------
+# 1. Compaction uses the MINIMUM revision across members. Compacting to a
+#    revision a member has not reached wedges that member - measured on
+#    2026-10-07, when talos-cp-2 froze ~1.2M entries behind the leader and
+#    needed a reboot to rejoin.
+# 2. A member whose raft applied index lags the leader by more than 100000 is
+#    skipped and reported. Defragging a frozen member reclaims nothing.
+# 3. Members are defragged one at a time. A defrag pauses the member's apply
+#    loop for the duration of the file copy.
+#
+# Credentials: Secret etcd-defrag-creds in kube-system, SOPS-managed in
+# k8s/argocd/secrets/etcd-defrag-creds.enc.yaml (ksops generator 00-secrets).
+# Its client certificate is signed by the cluster's etcd CA and expires
+# 2036-10; rotate it before then by re-running the mint and re-encrypting.
+#
+# Companion alerts (monitoring): etcd_mvcc_db_total_size_in_bytes /
+# etcd_server_quota_backend_bytes > 0.8, and an etcd NOSPACE alarm alert.

+# running, read-only, in the same `iam` namespace until the last consumer moves.
+# Migration plan: ~/workplace/homelab-doc/ZITADEL_MIGRATION.html (outside git).
+#
+# Chart: zitadel/zitadel 10.4.0, app v4.19.2. The plan cites v4.19.4; the chart
+# has not published it yet. Pin the chart, never `*`, until the v4.19.4 chart
+# exists — a silent app bump invalidates the verified masterkey/passwap facts.
+#
+# URL: https://zitadel.riotpiao.com. TLS terminates at ingress-nginx, which
+# serves the wildcard riotpiao-com-tls as its default-ssl-certificate, so
+# ExternalSecure=true and TLS.Enabled=false (no per-rule tls: block needed).
+#
+# Database: CNPG cluster zitadel-db (wave 2). The DSN comes from CNPG's
+# generated `zitadel-db-app` secret. When ZITADEL_DATABASE_POSTGRES_DSN is set,
+# ZITADEL ignores the discrete Database.Postgres.* fields, so neither a
+# password nor a host is written into this file.
+#
+# Masterkey: Secret `zitadel-masterkey` (k8s/argocd/secrets/
+# zitadel-masterkey.enc.yaml), key `masterkey`, exactly 32 bytes. It wraps the
+# rows in system.encryption_keys, which encrypt every client secret and private
+# key. Losing it makes those values unreadable: keep the offline sealed copy.

+  # The chart marks eight objects as `pre-install,pre-upgrade` hooks (two
+  # ServiceAccounts, two ConfigMaps, Role, RoleBinding, zitadel-init,
+  # zitadel-setup), and one cleanup Job as `post-delete`. ArgoCD maps the first

+  # on EVERY sync, not only on a chart change.
+  #   - zitadel-init  (`init zitadel`) — schema step
+  #   - zitadel-setup (`setup`)        — first instance + iam-admin machine key
+  # On an initialized instance the setup step can fail, which aborts the sync
+  # before the Deployment is applied. If it succeeds instead, its
+  # machinekeyWriter container re-applies the iam-admin key Secret that
+  # Terraform reads, which silently rotates a credential in use.
+  # After the first sync reports healthy:
+  #   1. set configmapConfig.FirstInstance.Skip: true here — permanently: the
+  #      setup steps are schema-only once the instance exists, and Skip alone
+  #      stops the machinekeyWriter rotation

+  #   3. commit, sync once, then enable automated+selfHeal on the Application
+  # For a later schema upgrade, re-enable initJob.enabled only — never set

+One command replaces the manual sequence the Authentik script
+(scripts/iam/provision-rbac.py) used to do in a single pass. Phases run in a
+fixed order and every phase is safe to re-run:
+
+  keys         extract the iam-admin machine key and PAT from namespace iam
+  apply        terraform apply terraform/zitadel (project, roles, apps, machines)
+  secrets      write generated client ids/secrets back into the SOPS files
+  users        import one human user, converting the Django password hash
+  verify       check discovery, client count and the groups-claim gate
+
+`all` runs keys, apply, secrets, verify. It never runs users: the password hash
+must be supplied by a human, one user at a time.

+# terraform/zitadel — identity configuration for the ZITADEL instance
+#
+# Scope: this root module declares the objects INSIDE ZITADEL (org, project,
+# roles, OIDC applications, machine users, grants). It does NOT deploy ZITADEL
+# itself — that is ArgoCD's job (`k8s/argocd/apps/30-security.yaml`, values in
+# `k8s/infra/iam/zitadel-values.yaml`).
+#
+# Migration plan: ~/workplace/homelab-doc/ZITADEL_MIGRATION.html (outside git).
+# This file implements §1.3 (roles), §1.4 (machine users), §2.4 (grants) and
+# §6.2 (Terraform provider route). The claim-injection action of §1.3 lives in
+# `actions.tf` and stays disabled until the live go/no-go gate proves it.
+#
+# Authentication to ZITADEL uses the `iam-admin` machine key that the chart's
+# setup job writes to the `iam-admin` Secret in namespace iam:
+#
+#   kubectl -n iam get secret iam-admin -o jsonpath='{.data.iam-admin\.json}' \
+#     | base64 -d > ~/.config/zitadel/iam-admin.json
+#   chmod 600 ~/.config/zitadel/iam-admin.json
+#
+#   export ZITADEL_JWT_PROFILE_FILE=$HOME/.config/zitadel/iam-admin.json
+#   terraform -chdir=terraform/zitadel init
+#   terraform -chdir=terraform/zitadel plan
+#
+# State is LOCAL and git-ignored (`terraform/*.tfstate` in .gitignore). That is
+# a deliberate first step, not the final answer: §8 risk 8 of the plan names
+# state drift as a blast-radius item. Move the state to MinIO before a second
+# operator ever runs `apply`. No secret is written to state except the generated
+# client secrets and machine keys, which are marked sensitive — they still land
+# in the state file, so treat that file as a secret.
