feat(ops): 实现工单统计看板功能

1. 修复 MyBatis 类型安全问题
   - 创建 9 个 DTO 类替换 List<Map<String, Object>>
   - 修复 @MapKey 错误，使用强类型返回值

2. 实现工单统计看板 5 大功能
   - 漏斗统计：支持时间范围过滤
   - 时段热力图：改为近 7 天，Y 轴显示日期（MM-dd）
   - 功能类型排行：替换区域排行，JOIN ops_bus_area 表
   - 今日工单时段分布：X 轴优化为每 2 小时展示
   - 近七天客流统计：独立接口，支持工作台实时趋势

3. 字典转换实现
   - 新增 DictTypeConstants.OPS_AREA_FUNCTION_TYPE（保留供未来扩展）
   - 使用硬编码 Map 实现功能类型中文转换（性能最优）
   - 添加 TODO 说明未来可切换 DictFrameworkUtils

4. SQL 优化
   - 功能类型统计：INNER JOIN ops_bus_area 表
   - 热力图查询：按日期和小时分组统计
   - 时段分布：仅统计当天数据

5. 缓存策略
   - 看板统计：5 分钟缓存（@Cacheable）
   - 客流监测：5 分钟缓存
   - 防止高并发查询压力
