fix(otel): prefer OTLP over console exporter when endpoint is set

Console exporter ran alongside OTLP on deployed environments (ASPNETCORE_ENVIRONMENT=Development), flooding CloudWatch API logs with Activity/metric traces. Now uses OTLP when OTEL_EXPORTER_OTLP_ENDPOINT is present, falling back to console only in pure local dev.
