- Fix OTel custom metrics not reaching Prometheus: ESM static import hoisting caused metrics.getMeter() to run before sdk.start(), getting NoopMeterProvider. Changed to lazy-init pattern so instruments are created on first use after the SDK configures the real MeterProvider. - Fix Grafana dashboards job labels: OTel adds service.namespace prefix (job=farmafinder/farmafinder-backend), updated queries to use regex match (job=~".*farmafinder-backend"). - Fix histogram metric names: OTel appends unit suffix (_milliseconds) to histogram names (e.g. http_request_duration_ms_milliseconds_bucket). Verified: app_heartbeat_total, http_requests_total, db_query_duration_ms, redis_cmd_duration_ms, and all other custom metrics now flow correctly through OTLP -> Alloy -> Prometheus remote_write.
