security: bind to 127.0.0.1 by default behind a reverse proxy

New HOST env (default 0.0.0.0 for Docker/back-compat). The VPS installer now
writes HOST=127.0.0.1 and Docker maps the host port to loopback (127.0.0.1:3000:3000)
+ overrides HOST=0.0.0.0 inside the container — so the app is never reachable
directly on its port from the internet, only via the proxy. .env.example defaults
to 127.0.0.1 (manual installs); docs explain it. Existing installs hardened on
re-run of install.sh.

+By default the app binds to `127.0.0.1` (via `HOST` in `.env`), so only your
+reverse proxy can reach it — not the open internet. Local testing on the same
+machine (`localhost:3000`) still works. Only set `HOST=0.0.0.0` if you need direct
+external access without a proxy (then open the port in your firewall and add HTTPS
+yourself).

 (`cwebp` is optional — `apt install webp` — for WebP image conversion.)
