renjianbo 97ad453e89 feat: implement serve-first-pay-later order flow ...

- Redesign order status: 0待接单→1已接单→2服务中→3待支付→4已完成
- Backend: startService now requires status=1, completeOrder sets status=3
- Backend: payment callback sets status=4, only status=3 can pay
- Backend: cancel only allowed at status 0/1 (not during service)
- Mini-program: update status labels and payment button to status=3
- Android: TobeSerFragment queries status=1, SerFragment queries status=2
- Update all status comments and UI mappings across three platforms
