Use the new `started_at` param on `job` in the UI

Use the new started_at param on job in the UI.

This is because the ruby method started? method was buggy returning true, false and nil or a timestamp. We are making started? function based on ruby conventions, but the frontend still needs the timestamp.

Draft status because this MR depends on: !85513 (merged)
