借款登记支持上传原借入回单识别预填（09-17-company-loan-principal-repayment）

- 新增识别与保存接口：可读 PDF 本地解析，必要时有界调用现有回单 OCR；预填上下文加密绑定经办人、文件和 30 分钟
- 适配建行单位客户专用回单表格版式：按位置归行排序、竖排栏头、顶行无标签日期、大小写金额
- 拦截非最终、失败/处理中、多笔交易（含跨页无关联、编号冲突）、非人民币、公司支出和其他收款主体
- 金额、日期、编号整段校验；借款与原件同事务保存，失败回滚并清理对象；同一出借人原件唯一
- 保存绑定所选出借人版本；前端冻结核对时版本，迟到结果与切换账号不覆盖、不重发
- 测试：单测、隔离 HTTP/浏览器、变异；对账浏览器场景固定 UTC；五轮独立复核通过
- 无新增迁移
