test(e2e): mocked Codex device-flow + insights regenerate specs

codex-flow.spec.ts intercepts /api/auth/codex/device-start +
device-poll + /api/insights/settings to drive the UI through the
three-state machine (CTA → device-code panel → "ChatGPT connected"
badge) without touching auth.openai.com / chatgpt.com.

insights-generate.spec.ts mocks /api/insights/generate with the
canonical InsightResult shape (changed/stable/drivers/nextSteps/
confidence/limitations) and confirms the regenerate button surfaces
the inline success message — the AI provider stays uninvolved.
