feat(cash): 智享通凭证JSON直传导入端点 vouchers-json (zxt-cma-import-v1)

- 新端点 POST /api/cma/cash/import/vouchers-json (X-BOT-KEY鉴权, 独立router避开require_role)
- 兼容三种body: 裸rows数组 / {rows} / {datasets[0].rows} 整包
- 凭证级借贷平衡(替代批级, 已知单边30694记异常拒收), 结转行summary识别
- 日期从summary前缀解析, 无日期行pending拒收(不冒充文件时间)
- 科目解析: 行内subject → DB zxt_account_dict → body subject_map, 未命中拒收
- 幂等: 内容指纹batch + import_logs去重 + 行级业务键防重复
- entity默认1(陕西酣客), active校验; 不触发现金流联动(凭证未证实权威)
- 验收脚本 scripts/verify_zxt_vouchers_json.py 12/12 PASS (SQLite本地)
