* fix(helm): make the gateway init containers' image and resources configurable
init-home and init-extensions hard-coded busybox:1.36 and set no resources.
Clusters that pull only from a mirror could not start the gateway, and a
namespace ResourceQuota on limits.* rejected the pod, although every main
container already has a configurable image and requests+limits.
Add gateway.initContainers.image (repository/tag, default busybox:1.36, same
convention as nginx.image) and gateway.initContainers.resources (modest
requests+limits by default, matching the chart README's resource defaults).
Add a helm-template test for the defaults and the overrides.
