refactor: redesign order flow - serve first, pay later

- Redesign order status flow: 0待接单→1已接单→2服务中→3待支付→4已完成
- Allow service start from status 1 (removed payment barrier)
- Add payment entry after service completion (status 3)
- Update Android/miniprogram UI status mappings
- Add order flow design document to docs/
