feat(project): 主项目详情资源列表增加「涉及的子系统」字段

- ResourceVO 新增 subProjectName(资源所属子项目/子系统名称, 多个以、分隔)
- ProjectServiceImpl.getDetail: 主项目聚合资源时, 按 project_resource 关联
  回填每条资源所属子项目名(仅主项目填充, 子项目自身详情留空)
- 前端 ProjectDetail.vue 关联资源表格新增「涉及的子系统」列(subProjectName)
- 离线重编译重打包为 resource-platform-v6.jar 并重启(8080); 端到端验证通过
  (主项目'快递1.0系统'聚合资源显示 涉及的子系统='堡昕德小程序')
- build_v6.py(全量编译+重打包)/ extract_deps.py(抽依赖) 入库为无 Maven 环境重部署工具
