fix: update integration tests for auto-auction behavior

The POST /swarm/tasks endpoint now triggers an automatic auction via
asyncio.create_task. Tests must allow tasks to be in bidding, assigned,
or failed status since the background auction may resolve before the
follow-up GET query.

All 895 tests pass.
