docs: never store argocd admin password hash in git

Drop .env/envsubst/bake-hash-into-values.yaml flow entirely. Chart's
configs.secret block is removed for good, so the rendered manifest
never declares admin.password/admin.passwordMtime. Password hash is
set once directly on the live argocd-secret via kubectl patch, and
survives every self-heal sync since ArgoCD never owns those fields.

-ArgoCD won't run `envsubst` when it self-manages — replace the placeholder with the real hash so future syncs work:
+Set it once, straight on `argocd-secret` (the Secret ArgoCD actually reads) — never in `values.yaml`, never committed to Git:
 
 ```bash
-source .env
+read -s -p "ArgoCD admin password: " PW; echo
-sed -i "s|\$ARGOCD_ADMIN_PASSWORD_HASH|$ARGOCD_ADMIN_PASSWORD_HASH|" manifests/argocd/values.yaml
+HASH=$(htpasswd -nbBC 12 "" "$PW" | tr -d ':\n' | sed 's/$2y/$2a/')
+kubectl patch secret argocd-secret -n argocd --type merge -p \
+  "{\"stringData\":{\"admin.password\":\"$HASH\",\"admin.passwordMtime\":\"$(date -u +%FT%TZ)\"}}"
+unset PW HASH
 ```
 
-```bash
+**Why this stays stable across self-management:** `values.yaml` never declares `configs.secret.argocdServerAdminPassword`, so the Helm chart's rendered manifest never includes `admin.password`/`admin.passwordMtime`. Once ArgoCD self-manages (wave -1, `selfHeal: true`), it only reconciles fields present in its own rendered output — it has no opinion on keys it never declared, so your patched hash survives every sync, forever. If that block is ever added back to `values.yaml`, the next self-heal overwrites it — don't add it.
-git add manifests/argocd/values.yaml && git commit -m "set argocd admin password hash"
-```
 
-```bash
+To rotate later: repeat the same `kubectl patch` with a new hash and a new `admin.passwordMtime` (ArgoCD only accepts the change if the Mtime also changes).
-git push origin main
