t142: 雲端子庫顯示同步幾張卡＋幾個三元組（政府專案驗收需求）

leo 07-29：「要在雲端子庫顯示同步了幾個 wiki，既然這樣也同步顯示有幾個三元組，
這是為了政府專案驗收。」

kbdb 兩支統計端點：
- entries.ts: COUNT(DISTINCT page_name) AS card_count
  ⚠️ 必須 distinct——算 block 數會膨脹 3-5 倍，政府驗收看到假數字比沒數字更糟
- records.ts: COUNT(*) AS triplet_count（三元組本來就算全部）
portal.ts 聚合兩者掛進庫目錄；前端 index.html 顯示。

驗：卡數確為 COUNT(DISTINCT page_name)／前端內嵌 JS node --check 全通過
（07-29 白畫面事故教訓）／portal-admin 測試 34 passed（改動前 31 passed，
唯一的 1 failed 是既有債：GET /portal 回 404，改動前後相同，非本次造成）。

註：此為子 CC 完成後未 commit 的懸置工作，總管收工檢查時發現並補收。
