fix(web-ui): show live download % on YouTube import bar

The import queue row's progress bar read only `r.progress`, which pollRow
never updated numerically — it tracked asset.status (ingesting/processing/
ready) but not a percentage, so the bar sat at 0 until the asset flipped to
ready, then snapped to 100 ("blank until it finishes").

pollRow now also fetches GET /jobs/<jobId> and feeds the BullMQ job's numeric
progress (worker emits 2..100 across the yt-dlp download + S3 upload) into the
bar, so it fills during the download. Falls back to status when the job is
evicted post-completion. Also reaffirm 'downloading' label while ingesting and
poll a bit faster (2s) since short clips finish quickly.
