feat: v0.5.2 - daily trend refactor + provider/model two-level drill-down

- Dashboard: 用量趋势卡片改为外层 tab 容器（下划线 tab），移除卡片标题与内部 pill 切换器
- 用量趋势: 新增 供应商模型用量趋势 tab，与 模型用量趋势 并列
- 供应商 tab 弹窗: 每日用量详情改为两级（供应商 → 模型）分组
- 后端: DailyRow 新增 by_provider_model 嵌套聚合
- 前端: DailyBars 通用化（dimension/colorMap），DailyDetailModal 按 tab 维度渲染
- i18n: 新增 providerDistribution（中/英）
- 版本: 0.5.1 → 0.5.2（tauri.conf / Cargo.toml / package.json / README）
