🪵 feat: Add OpenTelemetry Logs Pipeline via Winston Bridge (#15565)

Browse source 
Exports application logs as OTel log records when OTEL_LOGS_ENABLED=true,
correlated with the active trace, and gates every signal explicitly so a
disabled signal never falls back to the SDK's default OTLP exporter.
Verified end to end over OTLP/gRPC against an in-process collector.
