Subject: [PATCH] fix(chart): InitContainer curl+REST API en lugar de
 bitnami/kubectl:1.30
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

bitnami retiro los tags semanticos minor (1.30/1.29/etc.) de Docker Hub
2026-05; solo quedan latest + digests. El InitContainer fallaba con
ImagePullBackOff en el smoke E2E DO (run 1511/1512 del tenant
91c93c9c060a48febb7874c87c1ce993).

Cambio:
- image: bitnami/kubectl:1.30 -> curlimages/curl:8.20.0 (Docker Official,
  tag estable).
- comando: kubectl get secret -> curl REST API kubernetes.default.svc con
  SA token + CA cert montados en /var/run/secrets/kubernetes.io/serviceaccount.
- Misma logica: 48 iteraciones x 5s = 240s busy-wait.
- El Role/RoleBinding (role-db-secret-reader.yaml) ya da el permiso get
  secrets al SA — sin cambios RBAC necesarios.
