feat(cost): 新增生产成本管理模块基础功能

- 新增成本项目配置（CostItem）实体、Bo、Vo、Mapper、Service及Controller，提供增删改查和分页查询服务
- 新增成本单价历史（CostPrice）实体、Bo、Vo、Mapper、Service及Controller，管理成本项目单价历史记录
- 新增生产成本明细（CostProdDetail）实体、Bo、Vo、Mapper、Service及Controller，记录生产消耗明细
- 新增生产指标明细（CostProdMetric）实体、Bo、Vo、Mapper、Service及Controller，管理生产指标计算
- 新增生产月报（CostProdReport）实体、Bo、Vo、Mapper、Service及Controller，提供生产月报管理功能
- 在klp-admin模块pom.xml中引入klp-cost模块依赖，并添加klp-cost模块到项目主pom.xml
