批次5：inventory服务下沉收口 + Pydantic v2 / datetime弃用清零
- inventory业务层下沉（薄路由+service orchestration模式）： - customer/supplier/warehouse -> master_data_service - material_routes（价格历史/趋势/供应商关联）-> material_service - product_routes（CRUD/BOM/from-task跨模块桥接）-> product_service - dashboard_routes（首页统计/低库存预警）-> dashboard_service - inventory侧新增service回归覆盖（dashboard 2 / master_data 10 / material 10 / product 14），含跨模块桥接测试种子 - Pydantic v2弃用清零：全仓14处 class Config 全部迁移到 model_config = ConfigDict(from_attributes=True)（含 shared auth） - datetime.utcnow() 弃用清零：auth_service 3处统一改 datetime.now(timezone.utc) - 同步文档：STATUS / ROADMAP / TECH_DEBT（D12清偿）/ AGENTS 代码地图 测试基线：126 passed, 4 skipped（无deprecation warning） Co-Authored-By: Claude Code <noreply@anthropic.com>
