Pass SENTRY_DSN env var through to the backend container so the Sentry SDK
actually ships exceptions to GlitchTip — the variable was written to
.env.staging by nightly.yml but never forwarded into the container.
Enable Spring Boot 4.0 ECS structured logging (LOGGING_STRUCTURED_FORMAT_CONSOLE=ecs)
so Loki receives single-entry JSON log lines with parsed log.level, enabling
detected_level filtering in Grafana instead of 50-line unlinked stack trace blobs.
Update Grafana Loki dashboard query from | logfmt to | json to match the new format.

Add obs-grafana service (grafana/grafana-oss:11.6.1) to docker-compose.observability.yml.
Datasources (Prometheus, Loki, Tempo) are auto-provisioned via
infra/observability/grafana/provisioning/datasources/datasources.yml with
cross-datasource linking (Loki traceId → Tempo, Tempo → Loki, service map via Prometheus).
Three dashboards are pre-loaded: Node Exporter Full (1860), Spring Boot Observability (17175),
Loki Logs (13639) — datasource template variables replaced with provisioned UIDs.
GRAFANA_ADMIN_PASSWORD added to .env.example.

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
