V3.49

- 分页基准从明细行改为单号：21 项单号不再被拆到 3 页

- 步骤 1a 构造 GROUP BY borrow_no 的 subquery（sort_key + status 聚合）

- 步骤 2 主查询 SELECT order_subq.c.borrow_no 一列，避免触发 PG GROUP BY 严格模式 (f405)

- 步骤 3 用 page_borrow_nos 拉明细，保留前端 groupMap 期望的 items 形态

- pagination.items 用 isinstance + hasattr(_mapping) 兜底提取纯字符串（修 psycopg2 can't adapt type 'Row'）

- service 加 try-except，路由层识别 500 透传 traceback

- status 过滤改为单号聚合（borrowed=至少一条未还，returned=全部归还）
