fix(kubernetes): quote storage values and guard bind-mount commands

Quote diskSize and storageClassName Helm template outputs to prevent
bare numeric or special-char values from causing YAML parse errors.

Also ensure mount-point directories exist before bind-mounting and skip
the mount when the target is already a mountpoint, avoiding failures
on node reboot or re-provisioning.
