feat(queue): enhance currently printing item display

- Add progress bar, time remaining, ETA, and layer count to currently printing item
- Remove duplicate formatDuration & formatETA functions, now imported from utils/dates
- Remove formatTime (duplicate of formatDuration)
- Update formatETA to support optional i18n translation
- Update translation: common.tomorrow
