Function export_trace_with_client

nodedb/src/control/otel/exporter.rs:288–301

Public OTLP trace export using a caller-provided shared client. The `SharedState` holds a single `Arc ` that alert, SIEM, and OTEL emitters all reuse — no per-call client construction.

(
    client: &reqwest::Client,
    timeout: std::time::Duration,
    url: &str,
    spans_proto_bytes: &[u8],
