Use hostpath instead of rancher (#896)

This pull request removes the local-path provisioner setup from the
`local-hostpath` overlay and switches volume provisioning from dynamic
PersistentVolumeClaims to a static hostPath mount. The main changes
simplify storage configuration by removing Kubernetes resources related
to dynamic provisioning and updating the deployment to use a direct
hostPath mount.

**Storage Provisioning Changes:**

* Removed the `PersistentVolumeClaim` definition, eliminating dynamic
volume provisioning for the workload.
* Updated `volumes.yaml` to mount the `/mnt/nvme-raid` directory
directly via a `hostPath` volume, instead of referencing a PVC.

**Kubernetes Resource Clean-up:**

* Deleted all local-path provisioner resources, including the
`ConfigMap`, `Deployment`, RBAC roles/bindings, service account, and
namespace, removing support for dynamic local-path volume provisioning.

* Removed the `StorageClass` definition for `local-path`, further
disabling dynamic storage provisioning.
