feat(elevator): 部署与 V1 对齐 Consul，Ribbon 固定 ninca-crk-std

- bootstrap：discovery.enabled=false、注册字段与 access-control，与 V1 fat-jar 一致（宿主机仍 192.168.3.12）
- application：v2-maven 使用 elevator-app、tomcat UTF-8；注释与静态 Ribbon 说明
- 新增 NincaCrkStdRibbonConfiguration + @RibbonClient，避免 Edgware 下 Feign 无可用实例
- deploy README 更新 Consul / ninca-crk-std 说明
