fix: 修复API Keys页面时间窗口进度条和Token数值显示问题

- 修复时间窗口限制的请求次数和Token使用量进度条不更新的问题
  - 在apiKeyService.getAllApiKeys()中添加获取当前窗口统计数据的逻辑
  - 从Redis读取rate_limit:requests和rate_limit:tokens键的值

- 优化Token数值展示，添加K/M单位格式化
  - UsageDetailModal组件中5处Token数值改用formatTokenCount
  - ApiKeysView模型统计中5处Token数值改用formatTokenCount
  - 统一使用K/M单位简化大数字显示
