/**
 * portal-auth P3 測試（design §1/§3.3/§3.4/§5/§6，Gitea #24/#25）
 *
 * 覆蓋（=tasks.md P3 測試項＋#24 驗收 3 的 server-side 證明）：
 *   1. /portal HTML 殼：200、brand、**零租戶字串/零 X-Arcrun-API-Key/零 Mira 字樣**
 *   2. /portal/data/search enforce：server 注入 owner_id＋library；caller 自帶
 *      owner_id/library 參數被靜默覆蓋（filter 繞不過的機械證明）；["*"]＝不注 library；
 *      空集合＝誠實空結果不打 KBDB
 *   3. /portal/data/entries/:id 逐筆驗庫：越庫 404、跨租戶 404、不存在 404（同一句，
 *      不洩存在性）、NULL library→general fallback
 *   4. graph D-4 粗閘：無來源庫權限 403（不打 plugin）；["*"]／有權 → 轉發
 *   5. workflows D-8：非 admin 403；admin 唯讀 list＋最近執行、回應無 webhook_url；
 *      workflowsVisible 單元（admin/all/off/壞值）
 *   6. /portal/session 能力欄位：graph_allowed / workflows_visible
 *
 * KBDB／graph-plugin 都打 fetchMock 假 host（wrangler.test.toml KBDB_BASE_URL=
 * https://kbdb.test、KBDB_GRAPH_URL=https://graph.test）＋disableNetConnect——絕不外連。
