Match the fixture to the frameless upstream URL

src/server/live.ts:231-235 sends /v1/live requests to https://chatgpt.com/backend-api/codex/live. The fixture in tests/server/audio-dictation.test.ts:67-77 matches only /v1/live and /realtime/calls, so the request falls through to fetchOriginal. The tests do not reach the invalid-answer or alias-registration branches, and fixture.creates[0] remains unset.

Update the fixture matcher to include the canonical /backend-api/codex/live path. The existing [200] outcome assertions then detect a missing or incorrect status recording. The LiveCallBindings.prototype.create mock is restored in finally and does not require a lifecycle change.

In `@tests/server/audio-dictation.test.ts` around lines 273 - 308, Update the test
fixture’s upstream request matcher in createFixture to include the canonical
/backend-api/codex/live path alongside its existing live endpoints, so the
invalid-answer and alias-registration tests exercise the intended mocked
upstream flow and populate fixture.creates.
