fix: localize queue overlay running and queued summary (#8919)

## Summary
- Localize QueueProgressOverlay header counts with dedicated i18n pluralization keys for running and queued jobs.
- Replace the previous aggregate active-job wording with a translated running/queued summary.

## What changed
- Updated `QueueProgressOverlay.vue` to derive `runningJobsLabel`, `queuedJobsLabel`, and `runningQueuedSummary` via `useI18n`.
- Added `QueueProgressOverlay.test.ts` coverage for expanded-header text in both active and empty queue states.
- Added new English locale keys in `src/locales/en/main.json`:
  - `runningJobsLabel`
  - `queuedJobsLabel`
  - `runningQueuedSummary`

## Testing
- `Storybook Build Status` passed.
- `Playwright Tests` were still running at the last check; merge should wait for completion.

## Notes
- Behavioral scope is limited to queue overlay header text/rendering.
