feat: 实现 Issue #41 - 实时流数据采集（MQTT/Kafka Consumer）

## 功能特性
- 新增 MQTT 客户端支持，实现物联网遥测数据实时接收
- 完善 Kafka 消费者，支持多来源数据接入
- 添加数据验证和质量检查机制
- 新增数据统计和监控功能

## 主要改动
### MQTT 支持
- 新增 MQTT 配置类和连接工厂
- 实现 MQTT 消息接收和处理服务
- 添加 MQTT 控制命令发布功能
- 创建 MQTT 控制器 API

### 数据处理
- 完善 DataCollectService，支持 MQTT/Kafka 多源接入
- 添加数据验证工具类，确保数据质量
- 新增数据统计服务，提供多维度的数据统计

### 架构优化
- 规范指标类型枚举
- 添加数据质量评分机制
- 完善错误处理和日志记录

## 技术细节
- 使用 Eclipse Paho MQTT 客户端
- 集成 Spring Integration MQTT
- 支持 TDengine 时序数据库写入
- 实现数据质量验证和范围检查

## 测试
- 完成基础功能实现
- 添加数据验证测试
- 验证 MQTT 和 Kafka 消费者正常工作
