The ntfy service was configured with no published host port, on the
assumption that the public reverse proxy shares the compose network and
can dial ntfy:80 directly. It does not — Pangolin runs outside the
compose network and reaches every service through a published host port
(exactly why `app` publishes 3000). With no published port there was
nothing for the notification subdomain to forward to, so push delivery
could never work in production.
Publish container :80 on a host port (NTFY_HOST_PORT, default 2586,
binds 0.0.0.0 like `app`) and correct the now-inaccurate comments in
docker-compose.yml and ntfy/server.yml. Document NTFY_HOST_PORT in
.env.example. No code change — deploy config only.
