feat: 实现阶段二实体体系——AI预处理真实化+实体CRUD+审核归一化

- 新增 entities 数据表(含迁移)、Entity 类型、DAO 层完整 CRUD
- AI 预处理管道接入真实模型(generateText)，输出结构化 JSON(摘要+规范化内容+候选实体)
- 模板接口重构为 {systemPrompt, buildUserPrompt, parseOutput}，general/meeting 模板真实化
- 新增 5 个实体路由端点 + 实体管理前端页面(列表/详情/编辑弹窗)
- 审核面板增强：展示 AI 预处理结构化结果+候选实体归一化面板(合并/新建/选择/放弃)
- 素材通过时根据用户确认的候选实体写入 entities 表
- 工作台菜单新增"实体"入口
- 新增 entities DAO 测试(16)、processor 测试(11)、路由测试(8)，服务端 367 测试全部通过
- TypeScript 0 错误
