fix: Vite outputs directly to web/app/ — no dist copy needed

- vite.config.mts: outDir changed from web/app/dist to web/app
- .gitignore: ignore web/app/index.html + web/app/assets/ (build artifacts)
- deploy/deploy-frontend.sh: automated build+deploy+verify script

Deployment is now: bash deploy/deploy-frontend.sh
