用户反馈：底部只有「上一页 第 1 页 下一页」，看不到末尾/总页数。
原因：日志结果是 Loki 游标分页（cursor = 纳秒时间戳），本身不返回总数，
前端只能知道"有没有下一页"，算不出总页数。
解法：新增 POST /api/v1/logs/stats
→ 调 Loki /loki/api/v1/index/stats（只读 TSDB 索引里的 chunk 元数据）
→ 返回 {streams, chunks, bytes, entries}
→ 前端用 entries / limit 得到总页数
实测成本极低：1h 51ms、24h 30ms（3.28 亿条 / 44.2 GB）。
改动：
1. backend: services.LokiStatsFor + controllers.LogsController.Stats + 路由 /logs/stats
2. frontend: logsApi.stats；查询成功后拉取总数（复用同一 AbortController，
失败静默不影响日志展示）；计算 totalPages 传给结果面板
3. LogResultsPanel: 有总数时显示「第 N / M 页」，否则维持「第 N 页」
4. i18n: 新增 results.pageOfTotal（中英）
