Job completion progress in the timeline

Adds a job completion progress counter to the timeline table.

I don't think that we need such assumption, it might break if we had backfilled jobs, and the first collector can be offline/inactive/not relevant. What about something like this:

const jobs = collectors.flatMap(c => c.jobs).filter(j => j.requestTag === req.tag);
if (jobs.length === 0) {
    return "";
}
const completed = jobs.reduce((acc, job) => {
    if (job.status === "Failed" || job.status === "Success") {
      acc += 1;
    }
    return acc;
  }, 0);
return `${completed} / ${jobs.length}`;

Also, we already have the same check for "Failed" / "Success" when determining the collector status. It would be nice to separate that logic into a shared function, something like function isJobCompleted(job: BenchmarkJob): boolean.

The comment on top of the function can be removed now.
