feat: show active jobs label in top menu (#8169)

Replace the top-menu queue history icon with a localized “N active”
label so active jobs are visible at a glance.

Requested as part of the new
[designs](https://www.figma.com/design/LVilZgHGk5RwWOkVN6yCEK/Queue-Progress-Modal?node-id=3381-6181&m=dev).

I checked all failing snapshots and they are all expected (1 flaky).
