feat: 重新设计资产页面，去掉首页Tab

主要修改:
1. main_page.dart - 底部导航栏
   - 移除首页Tab
   - 保留4个Tab: 行情、交易、资产、我的

2. asset_page.dart - 资产页面重新设计
   - 顶部: 总资产估值卡片（显示总资产和今日收益）
   - 中间: 4个操作按钮（充币、提币、划转、赚币）
   - 下方: 资产组合（3个卡片：资金账户、交易账户、赚币）
   - 底部: 代币列表（显示持仓详情）

设计风格:
- 采用钱包应用风格
- 卡片式布局
- 玻璃拟态效果
- 响应式设计

优化:
- 数据加载更可靠（fallback机制）
- 强制刷新数据
- 更清晰的信息层级
- 更好的用户体验
