avoid duplicate keys in JobList stories

The JobList Storybook warnings came from `buildList(10)` over a factory
configuration that reused a single prebuilt running job template,
including its ID. That generated duplicate React keys in the list.

Build running jobs one at a time so each entry gets a distinct factory
instance and unique `id`, eliminating duplicate-key warnings in story
execution.
