## Why
- terragrunt-enc source drifted from the live encapi ENC: it declares
prodnxsr0014-0019 as roles::base, but live ENC already classifies them as
roles::infra::k8s::compute (confirmed via node-lookup enc_role).
- terragrunt-enc is the single source of truth for ENC data, so the source
must match reality.
## How
- Change prodnxsr0014-0019.main.unkin.net role from roles::base to
roles::infra::k8s::compute, matching prodnxsr0004-0008.
- environment stays develop, consistent with the other k8s compute physicals.
