fix(codeapi-chart): avoid argo pvc binding deadlock

[rschlaefli]

Summary

• fixes the Argo CD sync deadlock for the CodeAPI packages PVC when the storage class uses WaitForFirstConsumer
• keeps the packages PVC as a retained normal resource, not a Helm hook
• applies the PVC in the same sync wave as the package-init Sync hook so the hook pod can bind the volume before deployments roll

Verification

• helm dependency build helm/codeapi
• helm template codeapi helm/codeapi -n codeapi -f /private/tmp/df-cloud-codeapi-stg-rollout/helm-charts/codeapi/stg/values.yaml
• git diff --check

Rendered staging chart now has:

• PersistentVolumeClaim/codeapi-packages: argocd.argoproj.io/sync-wave: "-5"
• Job/codeapi-package-init: argocd.argoproj.io/sync-wave: "-5"
• no helm.sh/hook annotation on the PVC
