fix(build): 私服 legacy 坐标分离、电梯 common/data 可编译与本地编译文档

- cloudwalk.legacy.public.version=3.7.2：result/web/serial 仍走私服；event/service 用 4.0.0
- common: spring-web；CollectionUtils for-each  Iterable 强转
- data: 反编译 DTO hashCode/import 修正（ImageRuleRef*、AcsElevatorDevice*）
- docs/build/本地编译说明.md；Maven工作区修订表补充 legacy 说明
