fix: renderPay 补传必选参数 target_terminal_type/initialize_code_type

支付宝实测报错: 参数[target_terminal_type]错误/参数[initialize_code_type]错误（INVALID_PARAMETER）。
枚举取值按接口文档实证（资金转账渲染支付接口）:
- target_terminal_type: 小程序=tinyapp / PC端=PC，本产品为 PC 网页收银台取 PC
- initialize_code_type: 短链接=SHORT_URL / 吱口令=SHARE_CODE，PC 端跳转取 SHORT_URL
测试: renderPay_returnsPayUrl 增 ArgumentCaptor 断言，54/54 Service 全绿
