[feat] Show "Finished in" duration for completed jobs in cloud (#6895)

## Summary
In cloud distribution, completed jobs now show "Finished in Xh Ym Zs" as
the primary text instead of the filename.

- Uses `formatDuration` to display time as `1h 30m 45s`, `30m 45s`, or
`45s`
- Gated with `isCloud` - non-cloud continues to show filename
- Added i18n key `queue.completedIn` for localization

Filename is not fetchable right now in cloud. This is what design wanted
as the alternative.
