fix(desktop): 让账号页设备 ID 可展开

[Xavier-Trump]

Summary

• 让 Desktop 设置 > 账号里的桌面设备卡片支持展开完整设备 ID。
• 默认仍显示短 ID，展开后用可换行等宽文本显示完整 ID，避免横向溢出。
• 补充中英文 aria 文案和 SummaryCard focused 单测。

Test Plan

• python JSON parse for Desktop zh/en locales
• cd app/desktop && corepack.cmd pnpm exec vitest run src/components/settings/primitives/SummaryCard.test.tsx --reporter=dot
• cd app/desktop && corepack.cmd pnpm typecheck
• cd app/desktop && corepack.cmd pnpm exec eslint src/components/settings/primitives/SummaryCard.tsx src/components/settings/primitives/SummaryCard.test.tsx src/components/settings/sections/AccountSection.tsx
• cd app/desktop && corepack.cmd pnpm test:ci
• Playwright probe at 1556x911 and 900x820: account page opens in zh, full device ID hidden before expand, visible after expand, aria-expanded toggles, no horizontal overflow
• git diff --check

Notes

• Default cd app/desktop && corepack.cmd pnpm test still hits the existing shared-ui duplicate React invalid-hook-call debt in ../shared tests; CI split entrypoint test:ci passes.
