Add optimization status indicators to domain selection

- Show [NEEDS OPTIMIZATION] or [OK] status next to each domain
- Helps users quickly identify which domains require work
- Uses detect_php_config_issues to check critical/high severity issues
- Provides visual cues for faster domain selection
- Only shows status for optimize action to reduce processing overhead
