Copy the plugin staging script into the build that needs it

Browse Source 
`npm run build` fires a `prebuild` hook that runs
`node ../scripts/stage-frontend.mjs`, the script that copies each plugin's
frontend into the Vite tree and codegens routes.gen.js. The Dockerfile's
frontend stage copied `frontend/` alone and flattened it to the stage root, so
`../scripts` resolved to `/scripts`, which does not exist. Every image build
since the staging script landed has died there on `Cannot find module`.

The stage now keeps the repo-relative layout - frontend/, scripts/ and plugins/
as siblings under /build - because the script resolves its repo root as its own
directory's parent. The final stage copies from /build/frontend/dist to match.

Verified with a real build, not by inspection: 16 plugin frontends staged, vite
produced dist, and the finished image carries frontend/dist with 241 assets.

This also unblocks SITE_PLUGINS lean image builds, which until now only
scripts/build-site.sh could do.
