- transport 新增 feign /feign/client/driver/sync-mobile：按 user_id+tenant_id 找档案，
  档案 mobile 等于账号旧号时只改 mobile 一列（带 driving_vehicle 原值），已是新号幂等成功，
  找不到或判据不满足返回 synced=false 与原因
- blade-system updateUserWithPhoneSync：账号等于旧号时跟随新号、补账号唯一性校验，
  本地写库后调 feign 同步档案；同步失败只记日志，不回滚账号更新。登录链路仍走 updateUser
- App 内改号改调 updateUserWithPhoneSync
- bindOpenId 改为覆盖写：不再拦截已绑定其他 openid 或 openid 属于其它账号
