Details 
Add Grafana row to the observability services table, Grafana access details
(URL, credentials, auto-provisioned datasources, pre-loaded dashboards), and
GRAFANA_ADMIN_PASSWORD to the env vars table in DEPLOYMENT.md.
Update C4 l2-containers.puml: replace placeholder Grafana entry with pinned
image version, expand observability boundary with node_exporter and cadvisor
containers, and add Rel() edges for Grafana → Prometheus, Loki, and Tempo.

f3f8345b03 feat(observability): add Grafana with provisioned datasources and dashboards 
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.
