RPF-WP-0046: periodic ESO database tokens and a daily renewer

The five dynamic-database ClusterSecretStores use 768h static tokens that
nothing renews; expiry revoked their DB leases on 2026-09-23 and recurs
around 2026-10-25. Kubernetes auth is not a drop-in fix: ESO v0.16.1 revokes
its login token after each reconcile, which revokes the leases it created.

- eso-token-renewer CronJob (ArgoCD draft, no RBAC, mounted Secrets).
- Attended periodic mint script for all five lanes.
- CronJob added to the platform-addons AppProject in git (not yet applied).
