Add OTEL tracing and logging to Erlang microservices (gateway, order, stock). Export telemetry to OTLP endpoint, log lifecycle events and HTTP requests.

Common failure modes

Models hallucinate non-existent Erlang packages. The Erlang OTEL ecosystem is poorly documented, leading to packages like `opentelemetry 1.4.2` that don't exist in Hex.

Example error

===> Package not found in any repo: opentelemetry 1.4.2
