feat: Complete intelligent pipeline optimization with Pattern-1 compatibility

- Frontend: Smart change detection (83% payload reduction)
- Backend: Self-aware processing functions skip redundant operations
- Assessment: Intelligent skip based on explainability_info presence
- Data safety: Fixed section management logic, Decimal serialization, URI handling
- Hybrid service: DynamoDB get + AppSync update for immediate UI feedback
- Pattern-1: Informative modal explaining BDA architecture differences
- Complete enterprise-grade optimization for agent analytics performance
