问题: 0.01天(约14分钟)显示为"今天过期",不够精确
原因: 使用Math.ceil向上取整,导致小于1天的时间都显示为1天

修复内容:
1. 改用Math.floor向下取整,更准确反映剩余时间
2. 新增diffMinutes和diffHours变量,支持分钟和小时级别显示
3. 优化判断逻辑:
   - 0-59分钟: 显示"X分钟后过期"
   - 1-23小时: 显示"X小时后过期"
   - 1天: 显示"明天过期"
   - 2-7天: 显示"X天后过期"
   - 7天以上: 显示具体日期时间

修改文件:
- frontend/app.js: formatExpireTime方法(第1317-1335行)
- frontend/share.html: formatExpireTime方法(第836-854行)

测试示例:
- 0.01天(14分钟) → "14分钟后过期 (2025-11-14 12:27)"
- 0.5天(12小时) → "12小时后过期 (2025-11-15 00:00)"
- 1天 → "明天过期 (2025-11-15 12:13)"
- 7天 → "7天后过期 (2025-11-21 12:13)"

关于过期文件清理:
已分析当前机制,过期分享无法访问但记录不会自动删除。
详细分析和解决方案见《分享过期处理机制分析报告.md》。
当前实现是安全的,自动清理功能可作为后续优化。
