/**
 * portal-auth P4 測試（design §5/§6，Gitea #24/#25）
 *
 * 覆蓋（=tasks.md P4＋總管派工驗收重點）：
 *   1. **最後一個 active admin 鎖死保護**：停用 → 409；降級 role=user → 409；
 *      「還有另一個 active admin」才放行；另一個 admin 是 disabled 不算數。
 *   2. 一次性密碼：新增未帶密碼 → generated_password 只在回應出現一次、明碼不落 KBDB
 *      （庫裡只有 pbkdf2 hash）；自帶密碼 → 回應無 generated_password。
 *   3. reset-password：回一次性新密碼；PATCH 進 KBDB 的是 hash 非明碼。
 *   4. 庫權限：PATCH libraries=["*"]（全庫）合法；空陣列/壞庫名 → 400。
 *   5. 庫目錄：POST 建庫寫 {tenant}::portal 子 namespace；PATCH graph_source boolean。
 *   6. /portal HTML 殼（P4 admin 頁）：admin view 存在；**仍零租戶字串、零 /kbdb/、
 *      零 X-Arcrun-API-Key**（P3 紅線在新增 admin UI 後不得回退）。
 *
 * KBDB 打 fetchMock 假 host（wrangler.test.toml KBDB_BASE_URL=https://kbdb.test）＋
 * disableNetConnect——絕不外連。UI 全流程由本機隔離雙 worker 端到端 curl 驗證（PR 證據表）。
