feat: 用户体验优化 — 首页加载/继续记账/登录恢复

## 首页加载优化
- 分级加载：首屏只请求 overview + recentTx（2个请求）
- 数据新鲜度：30秒内不重复请求
- 次要数据异步加载：budget + todayData
- 非关键数据后台加载：userInfo + notifications

## 继续记账功能
- SaveSuccess 组件新增「继续记一笔」按钮
- 新增模式显示继续按钮，编辑模式自动返回
- 继续记账时保留分类和日期，清空金额和备注

## 登录失败恢复
- 登录重试机制：最多3次，间隔1秒
- 失败后显示提示而非静默等待

## 群组账单逻辑修正
- 群组账单 = 所有群组成员的个人账单之和
- 修改查询：WHERE user_id IN (群组成员)
