feat(i18n): Dashboard 页面内容国际化迁移 — 3 组件(Dashboard/DashboardCharts/DashboardRecent)硬编码中文改翻译键 + zh-CN/en-US 新增 dashboard.* 121 键(241 total)

- Dashboard.tsx: 标题/副标题/刷新/服务器按钮/StatStrip 7 标签/概览卡片标题 全部 t() 化
- DashboardCharts.tsx: 云成本概览/Top5资源使用/费用分布/月度趋势/环比标签 i18n(computeMonthChange 用 i18n.t 避开非组件上下文)
- DashboardRecent.tsx: 告警消息/证书到期/发布历史/服务器状态/集群状态 5 卡片全量 i18n
- zh-CN.json/en-US.json: dashboard 命名空间扩展 stat/alerts/certificates/releases/serversStatus/clusters/cost/topUsage/system 9 子分组
- 翻译键总数 120→241 (zh-CN/en-US 完全对齐)
- tsc -b=0, npm build=✓(19.01s), 17/17 集成测试通过, Docker healthy
