"""Integration tests for the Console header (default-agent) endpoints.

These cover ``/api/console/*`` endpoints that resolve the active agent
via ``get_agent_for_request`` (header variant) rather than the
``/api/agents/{agentId}/console/*`` scoped variant. The inbox subset
of the same prefix is exercised separately in ``test_inbox.py``; this
module focuses on the remaining 4 header endpoints (chat/stop,
push-messages, debug/backend-logs, upload).

POST ``/api/console/chat`` (the main conversation submit) is
intentionally NOT covered here — it requires an LLM round-trip and
will be revisited in Sprint 2.3 with a mock LLM.
