feat(lotw): 漫游核验改用「当前定位 vs 证书台址」，移除记录网格核对

- 新增 LoTWPositionWarning + positionWarning(currentGrid, stationGrids)：当前定位网格不在
  证书台址网格集内 → 提示（4 位归一；任一侧缺失不报）
- ISettingsRepo.getCurrentGrid()：只读取「≤24h 系统最后已知定位」与「存储台址」中较新者，
  不写任何设置（避开 setStationPosition 的写副作用）
- 上传前核对弹窗（雷达 / 日志本两入口）改由 VM 在 prepare 后计算；雷达记录页新增提示行
  （stationMismatch，点击=跳转改台址并预填当前格）
- 移除旧「记录 vs 台址」核对：uploadGridWarning / LoTWGridWarning / preview.gridWarning 及
  相关 UI / 字符串全删；LoTWPositionWarningDialog 重命名替代 LoTWGridWarningDialog
- 测试：LoTWPositionWarningTest ×5 替代 LoTWGridWarningTest；domain 171 / data 116 / mutual 28 全绿
