fix: add chart-testing CI values for helm-charts lint-test

Add ci/ct-values.yaml that overrides the image to busybox so
chart-testing can install the chart on Kind without needing the
real operator image. Add commandOverride support to deployment
template and conditionally skip probes when overridden.
