feat(代理自充): AUG26-017 代理自充收款方式与线下预存款审批字段

- 受控配置新增代理在线自充允许范围（仅微信/仅支付宝/同时支持），读侧与创建侧取允许范围与可用商户池交集，两侧失败关闭
- 新增允许范围查询与修改端点，读限代理与平台账号、写限超级管理员，复用受控配置写服务留痕
- tb_agent_recharge_record 新增交易流水号、线下收款方式三列快照与其他凭证列（成对迁移 000213）
- 线下申请校验启用的收款方式字典项与必填交易流水号，交易流水号独立于在线渠道交易号、不参与去重
- 扩展 offline_recharge_approval 场景可映射字段白名单与字典引用保护
- 新增付款凭证识别能力与交易流水号预填接口，识别不落库、日志不记录载荷
