Problem

After running undeploy.sh, the kai-resource-reservation namespace is left behind. This namespace is created by the kai-scheduler but not removed during undeployment.

Expected Behavior

undeploy.sh should delete the kai-resource-reservation namespace when uninstalling kai-scheduler.

Reproduction

1. Deploy a bundle with kai-scheduler
2. Run undeploy.sh
3. kubectl get ns kai-resource-reservation still exists

Proposed Fix

Add kai-resource-reservation to the namespace cleanup list in the undeploy template (pkg/bundler/deployer/helm/templates/undeploy.sh.tmpl), alongside the kai-scheduler namespace.
