feat(dc): Complete DC Tool-B backend implementation (Day 1 rebuild)

Completed:
- Add 4 Prisma models (dc_health_checks, dc_templates, dc_extraction_tasks, dc_extraction_items)
- Implement 4 core services (HealthCheck, Template, DualModelExtraction, ConflictDetection)
- Create ExtractionController with 6 API endpoints
- Register routes and initialize DC module
- Fully comply with cloud-native development standards
- Reuse all platform capabilities (storage, logger, cache, prisma, LLMFactory)

Tech Highlights:
- Dual model cross-validation (DeepSeek-V3 + Qwen-Max)
- PII auto-masking (phone, ID card, name)
- 3-layer JSON parsing with fallback
- Dice Coefficient similarity algorithm
- Schema isolation (dc_schema)

Lines: ~1,320 lines (4 services, 1 controller, routes, Prisma models)
