后端 cache 已用 fetchLatestPgTotalMileageMap 在当日 source=NONE 时
回填该车 ln_vehicle_day_total_pg 最近一条 total_mileage，但前端
表格 / 卡片 / Excel 都用 isDataSynced && totalKm != null 判定，
未对接车被锁回「未对接」文案。

调整为：
- 今日里程仍按 isDataSynced 显示「未对接」（今天确实没增量）
- 累计里程只看 totalKm 是否为 null，未对接但有历史值的车现在能显示

实测 粤A03423F：source=NONE / dailyKm=0 / totalKm=9205.6
原来「总: 未对接」→ 现在显示 9205.6 km
