feat(design+desktop): 设置屏改版——卡片分组布局（12A 实测反馈，原型先行）

原布局「灰字组标题 + 通栏细线」平铺无体块感、行距不均、控件对齐参差。
改版（原型 SettingsTray 与实现 SettingsApp 同步）：

- 分组卡片化：组标题在卡外（12px text-3 加字距），每组一张 radius-lg
  卡片（复用 Card 组件），卡内行以内嵌分隔线相隔，页面 bg-app 底上
  卡片体块清晰
- 行规格统一：SettingRow 复用，右侧控件统一右缘对齐
- 时长余额改大数字排版（text-xl bold + 单位小字基线对齐）
- 载入动效：四组 40ms 级差上浮淡入（对齐浮层动效语言，快入慢出）
- 顶条标题绝对居中（mac 原生习惯），与红绿灯永不重叠；原型 MacWindow
  同步改居中
- 原型补齐「帮助」组与实现对位

双主题截图验收通过；三道闸全绿；vite 构建通过。
