refactor(analysis): 去掉排行 10/30/50 选择器,改为一次取 50 + 前端分页;零点结算昨天

CI / Frontend (lint + build + test) (push) Canceled after 0s

=== 1. 为什么去掉「显示条数」选择器 ===
topk 的 N 不影响查询成本(扫描的 chunk 集合完全相同),实测:
  topk(10)  17833ms / 11 条
  topk(30)  18019ms / 34 条
  topk(50)   7394ms / 54 条
  topk(100) 17553ms / 74 条
波动来自集群负载,与 N 无关 —— 它只决定最后返回多少序列。
所以"选 30"既不更快也不更慢,本质是个翻页开关;
而选它还要重新等一次十几秒的查询,纯亏。
改为:一次 topk(50),前端 10 条/页 → 5 页只需 1 次查询。
附带收益:占比的分母从"前 10 合计"变成"前 50 合计",更接近真实占比。
副标题明确写清"一次取前 50 个应用(占比按这 50 个合计计算)"。

=== 2. 零点结算昨天(daily volume)===
原来只有 30 分钟 ticker 回补,且启动时间不对齐整点 →
昨天最早的一段可能已经超出 Loki 24h 保留期被删,
结算结果系统性偏低,图上却标"完整一天",属静默错数。
新增 nextMidnightFinalize():每天 00:01 触发 FinalizeYesterdayVolume()
  - 昨天定稿 partial=false
  - 补一次条数(index/stats,一天一次可接受)
  - 顺带刷新今天 partial=true 的柱子
ticker 仍保留,负责当天数据的 30 分钟刷新。

=== 3. 顺带 ===
- 去掉每日量"其中 N 天平台没有留存记录"的提示文案(按用户要求)
- 修 QuickQueryTemplates.tsx 的未使用变量导致 tsc -b 失败
- 工作区里上一轮中断的"排行体积列"改动一并纳入(app-ranking 返回 bytes,
  TopAppsTable 增加体积列,快照记录 per-app 字节数)
