The admin UI is a traditional multi-page app that loads ~13 separate
vendor/app JS+CSS files on every full navigation; none were compressed and
Cache-Control was max-age=0 (Express's default), forcing a revalidation
round-trip for every asset on every page view. Add gzip (compression
middleware) and sane Cache-Control (7d for vendor libs under
/static-modules, 1h for the app's own /static JS/CSS, which isn't
cache-busted). Matches the equivalent fix in theta42/proxy.
