test(routers): PR6 T6.7 — POST /api/threads workspace_id integration

`create_thread` in `app/gateway/routers/threads.py` already relies on the AUTO sentinel default for ``ThreadMetaStore.create``, so once T6.1 landed the workspace_id was implicitly carried from the contextvar. This commit adds the integration coverage: TestClient + stub auth middleware + ``MemoryThreadMetaStore`` round-trip showing the persisted row carries the right ``workspace_id`` under two distinct workspaces. No production code change — the route wiring was correct, but the guarantee was previously only proven at the unit level.

+"""PR6 T6.7 — POST /api/threads writes workspace_id from contextvar.
+
+The `routers/threads.py:create_thread` path delegates to
+``ThreadMetaStore.create`` *without* an explicit ``workspace_id`` — it
+relies on the AUTO sentinel pulling the value from the active workspace
+contextvar that AuthMiddleware (or the test stub) sets. This test
+covers the integration through the FastAPI TestClient stack: post a
+thread under workspace A, then verify the persisted record carries
+``workspace_id="ws-alpha"``.
