…ilence detection Address visibility gaps reported by Portola — audio flows but no transcripts return with no log signal. Add session_id correlators on existing logs, log WebSocket connect/close lifecycle, periodic audio byte counters, warnings after 15s of recv silence, and logging of unhandled message types. URL is not logged (contains customer prompt/keyterms_prompt).
Previous cadence emitted a single warning at 15s and then went silent even if the stream stayed stuck. Now warns every 15s with the actual elapsed silent duration so ongoing stalls remain visible in logs.
Redundant with the recv-silence warning and per-turn speech_duration log already emitted at end-of-turn. If send_task completes ws.send_bytes, the bytes reached the socket — logging counts adds no diagnostic value.

Extends the DEBUG logging added in #5146.
