Creates the skeleton observability stack (no running services yet) that all
subsequent Grafana LGTM + GlitchTip issues depend on:

- docker-compose.observability.yml: external archiv-net join, obs-net bridge,
  named volumes for all five services, placeholder comments for each service
  group (Metrics/Logs/Traces/Dashboards/Error Tracking), startup-order note
- infra/observability/{prometheus,loki,promtail,tempo,grafana/provisioning/{datasources,dashboards}}/.gitkeep
- .env.example: new # --- Observability --- section with PORT_GRAFANA,
  PORT_GLITCHTIP, PORT_PROMETHEUS, GLITCHTIP_DOMAIN, GLITCHTIP_SECRET_KEY
  (with generation hint), SENTRY_DSN, VITE_SENTRY_DSN

Verified: docker compose -f docker-compose.observability.yml config exits 0
