metrics/display: iterable job status

Ruby version: 3.3 Rails version: 7.0 Sidekiq Pro: 7.2.4

I'm running our first iterable job and was surprised that the web ui doesn't have a way to show the iteration progress.

We're using the array_enumerator and I was hoping to see something like "running on item #{item}".

I didn't see a way to see this information in the released code or open issues/pull requests.

In the same vein, I see it the web ui has "Started". I hope hoped to see something like "iteration job start" and "current iteration start".

A tab like for batches would be a good affordance, I think.
