feat(dashboard): split user

Stats widget into 4 modular widgets

- Create userInfoWidget (avatar, name, level)
- Refactor userStatsWidget (stats bars only with smart sizing)
- Create userMoodWidget (mood emoji, conditions)
- Create userAttributesWidget (STR/DEX/CON/INT/WIS/CHA)
- Add category field to widgets for auto-layout grouping
- Register all new modular widgets in dashboardIntegration.js

All widgets include getOptimalSize() for smart content-aware auto-layout.
Part of Phase 1 & 3.1 of dashboard modularization plan.
