feat: E1002 顶部加设备电量/温湿度列＋server 四路上游并行拉取与响应预算

- 新增 SenseCraft 设备遥测客户端（api-key 走 .env），读电量/充电/温度/湿度，DEVICE_TTL 与设备 300s 上报周期同步
- 大时钟 F84 右侧一列三行左缘对齐：电池（充电绿／≤20% 红）、温度计＋蓝色水滴、星期日期（与时钟基线对齐）
- server 过期上游由串行改并行，整体最多等 FETCH_BUDGET 秒（默认 5）；超预算的一路本次用旧值、后台拉完回填缓存，同一路不重复实拉
- 此前串行且上游 socket 超时 30s，任一路卡住即整图拖到平台抓取超时；「多路 TTL 同时到期」猜想经日志核查不成立，排查顺序写入 CLAUDE.md
