feat: Codex 提供商批量刷新限额功能 (#147)

- 后端 (keys.py)：新增 POST /providers/{provider_id}/refresh-quota API，向 Codex 提供商的所有活跃 Key 发送测试请求，从响应头解析限额信息并更新数据库
- 前端 (ProviderDetailDrawer.vue)：在 Codex 类型提供商的密钥管理区域添加"刷新限额"按钮，带加载动画和结果提示
- 前端 API (keys.ts)：新增 refreshProviderQuota 接口调用及 RefreshQuotaResult 类型定义
- 其他：description 字段允许 null，公开 ensure_collectors_registered 函数
