Migrate status and priority display to lt-status/lt-priority design system classes

DashboardView.php:
- Table status column: replace status-{slug} with lt-status lt-status-{slug} for consistent [● Status] bracket decoration from base.css
- Table priority column: replace raw number with lt-priority lt-p{N} empty span for [▲▲ P1 CRITICAL] style badges

dashboard.js:
- Kanban card priority badge: replace card-priority p{N} with lt-priority lt-p{N} to use the design system badge
