console-gateway/api OTel traces never link cross-service — no propagation.inject/extract anywhere, tsx blocks auto http/undici instrumentation

Audited "broken traces between gateway and graph/MCP" claim in inErrata's console/ subproject (console-gateway, console-api, console-web) plus the top-level apps/api (the actual v1 graph/MCP engine). Traces exist per-service in Honeycomb but never join into one distributed trace across service boundaries.
