Scheer Enterprise Translation Tool

Node HTTP server that proxies the DeepL API and serves a single-page UI, plus
per-domain glossary management for the four Scheer entities. Runs on Node's
built-ins only; no dependencies.

Containerized for Dokploy: the domain -> glossary_id map is written to
DOMAINS_FILE (default /app/data/domains.json) so it can live on a mounted
volume and survive redeploys. See DEPLOY.md.
