问题描述：
- 认证中间件存储的 UserID 是 uint 类型
- 日志中间件和错误上下文错误地将其断言为 string 类型
- 导致所有认证请求在记录访问日志时发生 panic

修复内容：
1. pkg/logger/middleware.go
   - 修改 UserID 变量类型从 string 为 uint
   - 使用安全的类型断言 (uid.(uint))
   - 使用 zap.Uint 记录日志

2. pkg/errors/context.go
   - 修改 UserID 类型断言从 string 为 uint
   - 使用 strconv.FormatUint 转换为 string 用于错误上下文

影响范围：
- 修复所有需要认证的接口的 panic 错误
- 包括 /api/admin/shops, /api/admin/me, /api/admin/permissions 等
