/**
 * TC-AI-MODERATION-009 — Moderation UI surfaces (Playwright).
 * Source: spec `.ai/specs/2026-06-04-ai-input-moderation-and-safety-identifiers.md`.
 *
 * Covers the two new backend UI surfaces deterministically by stubbing the
 * data routes (the page chrome + components render regardless of the live
 * registry / DB):
 *   - `/backend/config/ai-assistant/moderation-flags` — audit DataTable.
 *   - `/backend/config/ai-assistant/agents` — per-agent moderation section.
 *
 * The chat enforced→rejection and chat-off→passthrough flows are intentionally
 * NOT exercised here: the moderation gate runs SERVER-SIDE inside
 * `runAiAgentText`, so `page.route()` cannot stub it, and a live-provider e2e
 * would be non-deterministic (it needs a real OpenAI key + model behavior),
 * which `.ai/qa/AGENTS.md` forbids. Those branches are covered deterministically
 * by the gate unit tests (`input-moderation-gate.test.ts`), the moderation
 * service tests, and the `<AiChat>` `moderation_blocked` render test.
