v0.6.2: 仪表盘布局重构 + 每日趋势折线图 + OpenCode Go/Zen 预设

仪表盘:
- 新增每日用量趋势折线图（Token/缓存命中率/请求数三线）
- 用量趋势 Tab 组（每日/模型/供应商模型）与模型表格同行等高
- 热力图独立整行，格子放大 16px
- 折线图坐标轴文字改 HTML 覆盖层（修复 SVG 拉伸变形）
- 表格 border-collapse + 行线与边框同色
- 模型表格估算标签行内显示（行高统一）
- 最近请求容器 max-h 限制
- 页脚归属放内容流末尾

模型唯一性:
- 获取模型列表时自动勾选已存在模型 + 已添加徽章
- 批量添加跳过同供应商已存在 model id
- onBulkAdd 同供应商 model id 去重

新增预设:
- OpenCode Go（套餐 subscription，带推荐链接）
- OpenCode Zen（按量 pay_as_you_go）

折线图优化:
- 缓存命中率 0-1 映射修复
- 请求数默认显示
- 直线连接 + 渐变填充
