feat: 租户详情优化 - 添加统计字段，移除最近列表查询

后端变更：
- TenantResponse 添加 classCount、lessonCount 字段用于统计显示
- TenantServiceImpl 添加 getTenantDetail() 和 buildTenantResponse() 方法
- 移除最近教师/学生/班级列表查询逻辑（性能优化）
- 新增 StudentClassStatus 枚举类

前端变更：
- TenantListView.vue 更新详情展示，使用统计数字替代列表
- admin.ts 更新 TenantDetail 类型定义

优化：
- ClassServiceImpl 和 StudentServiceImpl 代码优化

+
+## 工作内容
+
+### 租户管理详情页字段补充
+
+#### 背景
+超管端租户管理查看详情时，前端页面期望展示以下数据：
+1. 使用统计：教师数、学生数、**班级数**、**授课数**
+2. **最近教师列表**（姓名、手机号、状态）
+3. **最近学生列表**（姓名、性别、阅读数）
+4. **最近班级列表**（名称、年级、学生数）
+
+#### 修改内容
+
+**1. 后端 DTO 扩展** (`TenantResponse.java`)
+- 新增 `classCount` 字段 - 班级数量
+- 新增 `lessonCount` 字段 - 授课数量
+- 新增 `teachers` 字段 - 最近教师列表（`TeacherItem` 内部类）
+- 新增 `students` 字段 - 最近学生列表（`StudentItem` 内部类）
+- 新增 `classes` 字段 - 最近班级列表（`ClassItem` 内部类）
+
+**2. 后端 Service 层修改** (`TenantServiceImpl.java`)
+- 新增 `getTenantDetail()` 方法 - 返回完整的租户详情响应
+- 新增 `buildTenantResponse()` 方法 - 构建包含统计信息和列表的响应数据
+- 新增 Mapper 依赖注入：
+  - `ClazzMapper` - 班级数据访问
+  - `StudentRecordMapper` - 学生阅读记录访问
+  - `StudentClassHistoryMapper` - 学生班级关联访问
+
+**3. 后端 Controller 层修改** (`AdminTenantController.java`)
+- 修改 `getTenant()` 方法调用 `tenantService.getTenantDetail(id)` 返回完整详情
+
+**4. 前端类型定义更新** (`admin.ts`)
+- 扩展 `TenantDetail` 接口：
+  - 添加 `classCount` 和 `lessonCount` 字段
+  - `students[].classId` 改为可选字段（因为学生班级关联是可选的）
+
+**5. 前端详情组件更新** (`TenantListView.vue`)
+- 修改统计数据显示使用 `detailData.classCount` 和 `detailData.lessonCount`
+
+#### 技术细节
+
+1. **学生班级 ID 获取**：由于学生实体没有直接的 `classId` 字段，通过 `student_class_history` 关联表查询学生当前所在的班级 ID。
+
+2. **班级学生数统计**：通过 `student_class_history` 表查询每个班级的 ACTIVE 状态学生数量。
+
+3. **学生阅读次数统计**：通过 `student_record` 表统计每个学生的记录数。
+
+4. **教师授课次数统计**：通过 `schedule_plan` 表统计每个教师的排课数量。
+
+#### 验证步骤
+1. ✅ 后端编译成功
+2. ⏳ 启动服务测试（待用户验证）
+
+#### 文件清单
+| 文件 | 修改内容 |
+|------|---------|
+| `TenantResponse.java` | 新增字段和内部类 |
+| `TenantServiceImpl.java` | 新增方法和 Mapper 依赖 |
+| `AdminTenantController.java` | 修改详情查询方法 |
+| `admin.ts` | 扩展类型定义 |
+| `TenantListView.vue` | 更新详情展示 |
