feat(quota): add display names and descriptions to compute quota limits

Populate displayName/description on each spec.quota.limits[] entry so the
service-catalog quota fan-out stamps kubernetes.io/display-name and
kubernetes.io/description on the generated ResourceRegistrations. Portals
(cloud-portal Quotas) then render readable names (Instances, vCPUs, Memory,
Workloads) instead of raw compute.datumapis.com/* metric keys.

Requires the QuotaLimitSpec display fields from milo-os/service-catalog#41.
