Adds SealedSecret velero-s3-credentials in namespace velero, holding
the dedicated velero-prod Hetzner Object Storage access/secret key
(scoped only to the basicstack-velero bucket).
Sealed on cp-1 via /root/seal-velero-s3-credentials.sh with the
sealed-secrets-controller public cert; plaintext never left the host.
Only the in-cluster controller can decrypt.

Adds the SealedSecret for the Kopia repository password that the Velero
BackupRepository will consume once the Argo app lands. Raw password is
held on cp-1 (root:root, 0600) pending the CEO handoff to Vaultwarden
and the offline safe copy (DEV-571).
