perf(energy): SWR 缓存 + 自调度刷新，氢能总览 6s → 13ms

ci/woodpecker/push/woodpecker Pipeline was successful

Details

接口侧：
- cache.ts 改为 stale-while-revalidate：每个 key 自调度，TTL 到期前 5s 后台刷新，用户永远命中热缓存
- 闲置 10 分钟后停止调度，避免空跑
- loader 失败保留旧值 + 10s 后退避重试
- 所有 4 个端点支持 ?force=1 强制绕过缓存

前端 HydrogenOverview：
- 顶部加 RefreshCw 按钮（强刷绕过缓存），带旋转动画
- 显示"更新于 X 秒前"相对时间
- 刷新中：顶部 0.5px 流光进度条，不替换内容、不闪烁
- 60s 静默自动刷新（命中后端热缓存）

实测：cold 6.1s → 命中 13ms（470× 提速）

perf(energy): add 60s TTL cache for all 4 endpoints

Hydrogen overview was 1.8-2.0s (3 full-table aggregations on 66K rows).
With cache: cold 1 user/min eats the full query, all subsequent within
60s window return in ~10ms.

Implementation:
- New cache.ts with cached(key, loader) helper
- Per-key in-flight de-duplication: concurrent requests share one loader
- Each handler wrapped, cache key includes query params
  (e.g. "hydrogen/daily?range=last30&customer=external")
- TTL 60s as requested

Measured speedups:
- hydrogen/overview: 1.96s → 12ms (165x)
- hydrogen/daily:    270ms → 11ms (24x)
- electric/overview:  93ms →  9ms (10x)
- electric/monthly:   36ms →  9ms (4x)
