feat: 添加排队退出机制和样式优化

新功能 - 排队退出机制:
- 用户卖出 YT 改为申请退出，创建请求加入队列
- 显示队列进度信息（总请求数/待处理/已处理）
- 显示用户待处理请求列表
- 管理员配置区域添加批量处理退出功能

合约 ABI 更新:
- withdrawYT 返回 requestId
- getUserPendingRequests 获取用户待处理请求
- getQueueProgress 获取队列进度
- processBatchWithdrawals 批量处理退出

样式优化:
- LP 流动池页面彩色背景改为白灰色
- 金库交易页面硬顶 Swap 区域样式统一
- 硬顶判断条件修改为使用 totalSupply
