- Add logging to MetricsController: warn on parse failures, debug on
  received metrics, buffer depth on 503
- Add GET /api/v1/admin/database/metrics-pipeline diagnostic endpoint
  (buffer depth, row count, distinct agents/metrics, latest timestamp)
- Fix BackpressureIT test JSON to match actual MetricsSnapshot schema
  (collectedAt/metricName/metricValue instead of timestamp/metrics)
- Upgrade cameleer3-common from 1.0-SNAPSHOT to 0.0.3 (adds engineLevel)
