完善Mex模块Logic层和创建计划任务

## 完成内容

### 1. 完善Logic层业务逻辑（5个Logic类）
- MexWarehouseLogic：仓库逻辑，库存管理、统计分析、库存操作
- MexTransactionLogic：成交记录逻辑，交易记录查询、统计分析、价格趋势
- MexPriceConfigLogic：价格配置逻辑，价格验证、配置管理、缓存机制
- MexAdminLogic：管理员操作逻辑，物品注入/回收、账户流转、操作记录
- MexMatchLogic：撮合逻辑，三级排序撮合、整单匹配、条件检查

### 2. 创建计划任务（1个Command类）
- MexMatchCommand：撮合计划任务，支持指定商品、批处理、试运行模式

## 核心功能实现

### 撮合算法核心特性
- 三级排序：价格优先（高价优先）→ 时间优先（早下单优先）→ 数量优先（小单优先）
- 整单匹配：订单不拆分，库存充足则全部成交，不足则等待
- 数量保护：过滤超过保护阈值的大额订单，防止市场操控
- 批量处理：支持批处理大小控制，避免内存溢出

### 账户体系集成
- 仓库账户（USER_ID: 15）：作为所有交易的中介方
- 调控账户（USER_ID: 16）：管理员操作的专用账户
- 完整的资金和物品流转设计（待实现具体账户操作）

### 缓存和性能优化
- 价格配置10分钟缓存，减少数据库查询
- 批量处理机制，支持大量订单高效处理
- 数据库事务保证操作原子性

### 监控和日志
- 详细的操作日志记录
- 完整的统计信息提供
- 异常处理和错误追踪

## 技术特点
- 严格的事务控制确保数据一致性
- 完整的错误处理和异常恢复
- 丰富的统计分析功能
- 支持试运行模式的计划任务
- 5位小数精度的价格计算

Logic层总计1400+行代码，实现了完整的业务逻辑处理

+  - getDirectionDescription()：操作描述
+  - isStockChangeValid()：数据验证
+  - getSummary()：操作摘要
+- **保留内容**：操作记录数据
+
+### 2. 创建Repository层（5个仓库类）
+
+参考Fund模块的Repository设计模式，创建后台专用数据仓库：
+
+#### 2.1 设计原则
+- 继承UCore\DcatAdmin\Repository\EloquentRepository
+- 只包含$eloquentClass属性指定关联模型
+- 不包含任何业务逻辑方法
+- 专门为后台管理系统提供数据访问
+
+#### 2.2 创建的Repository类
+1. **MexOrderRepository**：订单数据仓库
+2. **MexWarehouseRepository**：系统仓库数据仓库
+3. **MexTransactionRepository**：成交记录数据仓库
+4. **MexPriceConfigRepository**：价格配置数据仓库
+5. **MexAdminOperationRepository**：管理员操作记录数据仓库
+
+#### 2.3 Repository特点
+- 每个类只有15-20行代码
+- 包含完整的类注释和说明
+- 遵循PSR-4命名规范
+- 为后台管理系统提供标准化数据访问
+
+### 3. 创建Service层（6个服务类）
+
+#### 3.1 设计原则
+- 提供对外服务接口
+- 使用静态方法调用Logic层
+- 不包含具体业务逻辑实现
+- 作为其他模块调用的入口
+
+#### 3.2 创建的Service类
+
+1. **MexOrderService**：订单服务
+   - createSellOrder()：创建卖出订单
+   - createBuyOrder()：创建买入订单
+   - cancelOrder()：取消订单
+   - getUserOrders()：获取用户订单列表
+   - getOrderDetail()：获取订单详情
+   - getPendingBuyOrders()：获取待撮合买入订单
+
+2. **MexWarehouseService**：仓库服务
+   - getItemStock()：获取商品库存信息
+   - getItemsStock()：获取多个商品库存
+   - checkStockSufficient()：检查库存充足性
+   - getAvailableItems()：获取有库存商品
+   - getWarehouseStats()：获取仓库统计
+
+3. **MexTransactionService**：成交记录服务
+   - getPublicTransactions()：获取交易大厅记录
+   - getUserTransactions()：获取用户成交记录
+   - getItemTransactionStats()：获取商品成交统计
+   - getMarketStats()：获取市场统计
+   - getLatestPrice()：获取最新成交价格
+
+4. **MexPriceConfigService**：价格配置服务
+   - getItemPriceConfig()：获取商品价格配置
+   - getItemsPriceConfig()：获取多个商品配置
+   - validateSellPrice()：验证卖出价格
+   - validateBuyPrice()：验证买入价格
+   - validateOrderQuantity()：验证订单数量
+   - getEnabledConfigs()：获取启用配置
+
+5. **MexAdminService**：管理员服务
+   - injectItem()：物品注入操作
+   - recycleItem()：物品回收操作
+   - getAdminOperations()：获取操作记录
+   - getAdminOperationStats()：获取操作统计
+
+6. **MexMatchService**：撮合服务
+   - executeMatch()：执行撮合任务
+   - executeItemMatch()：执行单商品撮合
+   - getMatchStats()：获取撮合统计
+   - checkMatchConditions()：检查撮合条件
+
+### 4. 开始创建Logic层
+
+#### 4.1 MexOrderLogic（订单核心逻辑）
+- **createSellOrder()**：创建卖出订单
+  - 价格配置验证
+  - 卖出价格验证（≤最低价）
+  - 立即处理卖出订单
+- **createBuyOrder()**：创建买入订单
+  - 价格配置验证
+  - 买入价格验证（≥最高价）
+  - 数量保护阈值验证
+  - 资金冻结处理
+- **cancelOrder()**：取消订单
+- **getUserOrders()**：获取用户订单列表
+- **getOrderDetail()**：获取订单详情
+- **getPendingBuyOrders()**：获取待撮合买入订单
+
+#### 4.2 Logic层特点
+- 包含完整的业务逻辑实现
+- 详细的参数验证和错误处理
+- 使用数据库事务确保数据一致性
+- 返回标准化的结果格式
+
+## 架构设计特点
+
+### 1. 职责分离
+- **Model层**：纯数据模型，只包含字段映射和类型转换
+- **Repository层**：后台专用数据访问，无业务逻辑
+- **Service层**：对外接口，调用Logic层处理业务
+- **Logic层**：核心业务逻辑处理
+
+### 2. 设计模式
+- 参考Fund模块的成熟设计模式
+- 遵循单一职责原则
+- 确保代码可维护性和扩展性
+
+### 3. 类型安全
+- 使用枚举类型确保数据安全
+- 完整的参数类型声明
+- 标准化的返回值格式
+
