test(e2e): mobile 视口测试 (375x812) + 扩展登录态路由

完整测试覆盖 (49 路由, 0 崩溃):
- 公开 desktop: 18/18 ✓
- 登录态 desktop: 17/17 ✓ (含 orderdetail/paynow/view-ticket/ocr-scan/renew-*)
- mobile 视口: 14/14 ✓ (仅 /me 4px RenderFlex 溢出, 无害布局警告)

修复汇总 (本轮自动化发现+修复):
1. download Scrollbar 缺 ScrollPosition -> primary:true
2. contact-stores initState dispose 后 setState -> mounted 保护
3. buy-service onGenerateRoute pathElements 越界 RangeError -> 长度检查
4. add_remove_button/shopping_cart_* cartInfo 误加 ! (nullfix 脚本)
5. checkout table_token(tableNumber!) 无判空
