feat(card-diy): 四组件字号定制化消费 + 契约测试(12 项)

- entry: 主/副标题与按钮字号内联消费(titleSize/subSize/btnSize, px→rpx ×2),
  文字箭头拆 btnArrowStyle(比按钮大一档=28rpx)
- list: 拆 gridNameStyle/scrollNameStyle/metaStyle/scrollMetaStyle, 横滑与
  人数徽标按 -1px 派生保持历史渲染; infoStyle 保持纯色(箭头/空态共用)
- mini(Show/Self 基件): name/cardTitle/sub/label/value/act/btn 七项字号内联,
  拆 cardTitleStyle/rowLabelStyle/detailTextStyle; labelStyle 保持纯色给图标/qr tip
- self: miniConfig 透传 7 个字号字段
- 新增 tests/diy-card-font-size.test.js: 三层口径契约(diy_view 默认值 ↔
  design.html 面板/重置 ↔ vue 消费) + 派生关系 + 颜色 value 兜底 + 反例自测

验证: 契约 12/12 绿; diy-card 全套测试 0 失败; E2E 截图目检通过
