Alloy 404s OTLP metrics, so each service gets a MeterProvider with a
PrometheusMetricReader (same Resource as traces) served by
prometheus_client on its own port instead of a FastAPI route: gateway's
port 8000 is publicly routed by Traefik, and the audit worker has no HTTP
app. Host/port come from OTEL_EXPORTER_PROMETHEUS_HOST/PORT. Setting the
provider before the instrumentors also turns on their built-in HTTP and
DB pool metrics.

setup_telemetry now instruments httpx and redis process-wide. Both patch
the client classes, so clients created at import time (gateway's
_proxy_client, common.redis_client) are covered too. httpx CLIENT spans
inject traceparent, so the downstream FastAPI SERVER spans join the
caller's trace. gateway and fraud get setup_telemetry, the FastAPI span,
and the OTLP auth header. All seven services now export traces.

common/telemetry.py builds the Resource, TracerProvider, BatchSpanProcessor
and OTLP/HTTP exporter by hand; sanctions calls setup_telemetry() at
import instead of running under opentelemetry-instrument. No instrumentor
is enabled yet, so sanctions emits no spans for now.
service.version comes from OTEL_RESOURCE_ATTRIBUTES: deploy.sh exports
DEPLOY_HASH (the server's HEAD after the pull) and compose falls back to
"dev". deployment.environment.name=prod is dropped.
