The 1h max-age set in Phase A caused a cache-vs-deploy mismatch when
Phase B refactored config-manager.js to lazy-load admin-overview.js et
al. The new index.html no longer eager-loads those scripts, but
browsers with the cached (pre-Phase-B) config-manager.js didn't do the
lazy-load either — so AdminOverview / AdminSystem / etc. were
undefined and the admin tools rendered 'failed to load' errors.
60s is the right balance: rapid in-session clicks skip the network
round-trip, but a deploy is visible within a minute. ETag-based 304s
still keep the per-request cost tiny when nothing changed.

Three WebUI cold-load wins:
1. DELETED containers/libreportal/frontend/js/components/config/config-manager-old.js
66 KB / 68189 bytes. Zero references anywhere in source or deployed
tree (confirmed via grep across containers/libreportal/). Pure dead
code from a previous refactor — removed.
2. ADDED `compression` middleware (defensive require)
Gzip-compresses JS/CSS/HTML/JSON responses. Typical ~70 % wire-size
reduction → the 1.7 MB cold-load drops to ~500 KB. New package.json
dependency; container's node_modules is baked into the image so the
require is wrapped in try/catch to degrade silently until the image
is next rebuilt (libreportal app install libreportal, or a full
deploy). Once active: free wire-size win on every response.
3. ADDED static cache headers via staticOptions on express.static
- JS/CSS/icons: Cache-Control: max-age=3600 + ETag
(1h browser cache, cheap 304 revalidation after)
- HTML files: Cache-Control: no-cache + ETag
(always revalidates so SPA shell updates land
immediately after a deploy; 304 if unchanged)
Repeat navigation in the same browser session skips ~25 script-tag
round-trips entirely.
Net effect once compression deploys:
- Cold load: 1.7 MB → ~500 KB on the wire (~70 % shrink)
- Warm load: 25 conditional requests → 0 (served from cache for 1h)
- Deploy lands: HTML revalidates immediately, JS/CSS picks up after 1h
or hard refresh
Phase B (defer non-critical scripts via SPA loadScript) and Phase C
(rebuild image / split the bind-mount story for node_modules) come
next; this commit is the safe Phase A foundation.
