Extract the args-override block into a helper function.

buildJobFromCronJob now combines deep-copy, name/uid validation, and four levels of nested type assertions for the args override in one function. This is flagged as high complexity by static analysis. Extract the args-override logic into a small helper to keep the function readable and testable in isolation.

+// jobSpec.template.spec.containers[0] with the supplied args slice.

197, Extract the args-override block from buildJobFromCronJob into a small
helper that accepts the copied job specification and args pointer, performs the
existing template/spec/container validations, and updates only the primary
container’s args. Replace the inline block with a helper call while preserving
all current errors and behavior, including leaving commands and sidecars
unchanged.
