refactor: replace direct WeChat/Alipay with unified pay-api gateway

Switch from direct WeChat Pay / Alipay integrations to the unified 宇之然 pay-api gateway (HMAC-SHA256 auth). Removes wechat_pay.py, keeps PaymentGateway abstraction, adds UnifiedPayService. Simplifies payment.py create_order to {plan, pay_type} params. Single webhook endpoint replaces separate WeChat/Alipay notify handlers.
