借款对账 SR-A/B：补证恢复与复核后释放（09-17-company-loan-principal-repayment）

保留原银行终态及依据，以恢复轮次绑定材料、候选和独立性；最终取消重验并原子消费批准、释放占用和记录审计。新增增量迁移、HTTP 回归及数据库保护。

验证：78 个迁移、HTTP 72 组、既有浏览器 7 组、数据库约束 9 组通过；7 个变异均被抓住。服务端首跑 4470 通过、6 失败、1 跳过，补齐 BIFF8 测试依赖后相关 146 项通过，未重跑完整套件。

限制：inline 主会话自查不等于独立复核，独立复核待完成；界面未完成，不能单独部署；真实回单待验。新恢复界面留待 S8，S4 另批，整体借款功能尚未完成验收。本次仅本地提交，不推送、不部署、不查询生产。
