## Summary
Adds **grep-friendly** `console` logging around the OpenTelemetry
metrics OTLP exporter in
[`packages/twenty-server/src/instrument.ts`](packages/twenty-server/src/instrument.ts)
so production / staging can confirm whether the app is exporting metrics
and why exports fail.
## Log format
- Prefix: **`[Twenty OTEL metrics]`** (easy to filter in Loki / `kubectl
logs | grep`).
- **Startup:** whether the OTLP reader is enabled, `exportIntervalMs`,
and endpoint as `protocol//host/path` only (no credentials).
- **First successful export:** one `console.log` per process (`first
export ok`) with metric data point count — avoids spamming every 10s.
- **Each failed export:** `console.warn` with result code, point count,
and serialized error (including nested `AggregateError` causes when
present).
