feat(ui): 排行榜与首页打卡卡片多项优化

排行榜性能:
- 客户端乐观缓存:进页面/切周期秒显旧数据,后台静默刷新,消除 2-3s 空白
- 云函数实例缓存 TTL 60s -> 5min,降低全表扫描频率

排行榜 UI:
- 空状态重设计:奖杯光环插画(径向光晕 + 闪光漂浮)
- 领奖台 slot 撑满对齐列表、金银铜底座配色、角标与昵称间距修复、底线对齐

首页打卡卡片:
- 火焰光晕脉动 + 72rpx 大数字 + 分段进度格子
- 计划 >10 天时进度退化为里程碑连续条

+ * switch while the cloud refreshes in the background.
+ *
+ * Freshness: entries older than LB_CACHE_MAX_AGE are treated as misses -
+ * the cached avatarUrl is a cloud:// temp URL (~2h TTL) and stale links
+ * render as broken images. 30min stays safely inside that window while
+ * still covering the common "switch tab / switch period" re-entry case.
