admin-panel: build into the folder the Docker image actually serves

The Dockerfile does `COPY dist /usr/share/nginx/html` and nginx serves that
folder's root, but vite's outDir was 'dist/export' (carried over from legacy's
vue.config.js). So the deployed root kept serving whatever index.html had been
committed at dist/ — a stale pre-port prototype build (lang="en", title
"Gold Bank — Admin Panel", no ant-design-vue at all, committed 2026-09-10 in
cea3b80). That artifact, not the current source, renders as an unstyled stack
of bullets and bare tables.

outDir is now 'dist' (and 'branchDist'), matching what the image serves and
matching apps/user-app's convention.
