"""Regression tests for issue #47237.

When the gateway persists a user message after a transient provider
failure (429/timeout/auth error), subsequent retries of the same
Telegram message must not stack duplicate user turns in the transcript.
The dedupe guard checks has_platform_message_id before persisting.
