feat(ai): 添加审批待办助手功能

- 集成 langchain4j 配置，支持多种 AI 模型包括 DashScope、OpenAI 和 Ollama
- 配置 MongoDB 存储聊天记忆，替换原有的 Redis 配置
- 添加审批待办助手的 Prompt 提示词文件
- 创建 ApproveTodoAgent 接口和相关配置类
- 实现 ApproveTodoIntentExecutor 意图执行器，支持审批相关操作识别
- 开发 ApproveTodoTools 工具类，提供审批待办的增删改查和统计功能
- 实现完整的审批流程管理，包括审核、驳回、修改、删除等操作
- 添加审批数据统计分析功能，支持状态分布和趋势图表
- 集成 ECharts 图表配置，便于前端展示统计结果
