Make data/ path configurable; preserve on frontend redeploy

- docker-compose: DATA_DIR env var controls data volume mount
  (defaults to ./data for local, /var/www/html/gmal-scope-builder/data on server)
- deploy.sh: resolve DATA_DIR from .env, default to persistent web dir
- deploy.sh: rm only frontend files from WEB_DIR, preserve data/ subdir
- .env.example: document DATA_DIR variable
