feat(admin): 添加系统日志功能

## 新功能

1. **系统日志数据库**
   - 新增 system_logs 表
   - 支持日志级别：debug/info/warn/error
   - 支持日志分类：auth/user/file/share/system/security
   - 记录用户ID、用户名、IP地址、User-Agent

2. **日志记录**
   - 用户注册成功/失败
   - 用户登录成功/失败（密码错误）
   - 系统操作（日志清理等）

3. **管理员API**
   - GET /api/admin/logs - 查询日志（支持分页和筛选）
   - GET /api/admin/logs/stats - 获取日志统计
   - POST /api/admin/logs/cleanup - 清理旧日志

4. **前端界面**
   - 日志列表展示（时间、级别、分类、内容、用户、IP）
   - 筛选功能（级别、分类、关键词搜索）
   - 分页导航
   - 清理旧日志功能
