Ullrich Schäfer 5c4b6fd9af Stop the caddy-502-rate alert firing on every deploy
The journal/planner deploy in cd-apps.yml does `docker compose up -d
journal planner`, which stops the old container and starts the new
one — Caddy keeps forwarding requests during the ~10–30s gap and
returns 502s. The caddy-502-rate alert (threshold > 0 for 2m)
correctly trips, every time.

Two production changes plus a long-broken workflow detail:

- infrastructure/Caddyfile — add `lb_try_duration 30s` /
  `lb_try_interval 250ms` to the journal and planner reverse_proxy
  blocks. Caddy now holds and retries the upstream for up to 30s
  during a restart instead of 502'ing immediately. Real outages
  (upstream unreachable longer than 30s) still 502 and the alert
  still fires for those.
- infrastructure/grafana/provisioning/alerting/alerts.yml — add a
  comment documenting why caddy-502-rate stays at threshold > 0:
  with lb_try_duration in front of it, the alert no longer
  conflates "deploy in flight" with "real outage."
- .github/workflows/cd-apps.yml — fix a long-silent bug: the
  Grafana deploy-annotation step was reading
  GRAFANA_SERVICE_TOKEN from `.env`, but the secrets file we scp
  to /opt/trails-cool is named `app.env`. The token check failed
  silently and the curl was being skipped on every deploy.
  Switching to `app.env` so deploys actually annotate Grafana.
