feat(17-02): install @vite-pwa/assets-generator, author logo.svg, add pwa-assets.config.ts

- Add @vite-pwa/assets-generator@1.0.2 as devDependency in apps/pwa
- Add pwa:icons script (pwa-assets-generator generate) to apps/pwa/package.json
- Approve sharp build scripts in pnpm-workspace.yaml (required for @vite-pwa/assets-generator)
- Hand-author apps/pwa/public/logo.svg: warm/rounded/at-home family scene with house, two adults, child, heart — square 512x512 viewBox, self-contained, text-free
- Create apps/pwa/pwa-assets.config.ts with minimal2023Preset, images: ['public/logo.svg'], no overrideManifestIcons
