Bug 1: 按「🔍 查看 Diff」失敗
  錯誤: 'DriftReportRepository' object has no attribute 'get_by_id'
  根因: DriftReportRepository 方法叫 get(), 其他 repo 都叫 get_by_id()
  修法: 加 get_by_id() alias, 對齊 repo 介面慣例

Bug 2: AI 研判內容被渲染成 code block + copy 按鈕
  根因: telegram_gateway line 1962 用 <pre> 包 diff_summary
       但 diff_summary 是 AI 研判敘述 + emoji 清單, 非 code
  修法: 移除 <pre>, 改以分隔線 + html.escape 純文字顯示

驗收:
- 下次 drift 卡片: AI 研判段落純文字(無紫色 code block + copy)
- 按「🔍 查看 Diff」→ 送完整 diff 詳情(非 AttributeError)
