Viktor Barzin 67d4ab3821 Fix celery metrics not reaching Prometheus and update Grafana dashboard ... Init OTel metrics at module level in celery_app.py so prefork child processes inherit the MeterProvider and PrometheusMetricReader from the parent. Previously, worker_process_init created a separate MeterProvider in each child, disconnected from the HTTP server in the main process — so all scrape/celery/OCR metrics were silently lost. Update Grafana dashboard with API Performance and Frontend Performance sections, synced from the live cluster dashboard.		2026-02-22 17:58:20 +00:00
