feat(运维监控): 重构仪表板布局和增强数据展示

主要改动：
- 重构仪表板为左右布局（5:7比例）
- 左侧：健康评分 + 实时信息（当前/峰值/平均 QPS/TPS）
- 右侧：6个卡片展示详细指标（3列x2行）
  - 总请求：请求数、Token数、平均QPS/TPS、平均延迟/TTFT
  - SLA：百分比、异常数、进度条
  - 延迟：P99/P95/P90/P50/Avg/Max（带颜色编码）
  - TTFT：P99/P95/P90/P50/Avg/Max（带颜色编码）
  - 请求错误：错误率、错误数、业务限制数
  - 上游错误：错误率、错误数（排除429/529）、429/529数
- 添加延迟/TTFT颜色编码（<500ms绿色，<1s黄色，<2s橙色，≥2s红色）
- 添加实时窗口选择器（1min/5min/30min/1h）
- 优化时间段选择器标签（"近5分钟"等）
- 完善中英文i18n翻译
- 数据库：添加Redis连接池字段（redis_conn_total, redis_conn_idle）
