Remove 5 dead components with zero production references

## Recommendation

### 🗑️ SAFE TO REMOVE (after verification)

Five components have zero production references (not imported in any template, router, or composable):

| Component | Location | Notes |
|-----------|----------|-------|
| `JobGroupsList` | Queue panel area | Not used in queue panel |
| `CreditTopUpOption` | Cloud credits | Unused cloud credit component |
| `CardTitle` | UI components | shadcn card part never imported |
| `CardDescription` | UI components | shadcn card part never imported |
| `DisplayCarousel` | Display widgets | Unused display widget |

## How to Fix

1. For each component, verify with: `grep -r 'ComponentName' src/ --include='*.ts' --include='*.vue'`
2. Confirm no dynamic/lazy imports
3. Remove files

## If Removing (⚠️ proceed with caution)

- [ ] No dynamic imports reference these components
- [ ] Check git blame — none are recently added WIP
- [ ] `CardTitle`/`CardDescription` aren't used by external consumers via the design system package
