"""Tests for the gateway /queue command handler (running-agent path).

/queue stores a turn-boundary follow-up in the adapter's pending queue
without interrupting the active run. The queued event must carry the
full payload — media attachments and reply context — not just the text.
Previously the handler rebuilt the event with only text/type/source/
message_id/channel_prompt, silently dropping any photo/document/reply
metadata the user attached to the /queue message.
