What do you want to work on?

I want to fix #2697 so users can set sandbox_uid and sandbox_gid in Helm values.yaml like every other Kubernetes driver field.

Why this change?

Small chart gap — every other K8s driver field is a value, these two aren't. We need it for a Dell multi-tenant setup wiring per-tenant sandbox UIDs into PowerScale Kerberos NFS through Helm + our operator. Onboarding tenants declaratively beats patching ConfigMaps by hand.
