[bugfix] Show active job count in assets sidebar badge (#9015)

## Summary
Assets sidebar badge now shows total active jobs (pending + running)
instead of only pending jobs, making it consistent with the "X active
jobs" label inside the panel.

## Changes
- **What**: Changed `iconBadge` in `useAssetsSidebarTab` from
`pendingTasks.length` to `activeJobsCount` (pending + running)
- Badge still hidden when QPO V2 is disabled (legacy queue)

## Review Focus
- Whether `activeJobsCount` (pending + running) is the correct metric
for the badge
