本次提交主要包含以下更新：
- **错误日志页面增强**:
- 重构了 [`app/static/js/error_logs.js`](app/static/js/error_logs.js) 中的分页逻辑，将样式控制移至 CSS，简化了 JavaScript 代码。
- 更新了 [`app/templates/error_logs.html`](app/templates/error_logs.html) 中的分页样式，使其与 `keys_status.html` 保持一致，提升了视觉统一性。
- 在错误日志页面新增了“清空全部”按钮，方便用户一键清除所有错误记录。
- 调整了错误日志表格头部的文本颜色为白色，以改善深色主题下的可读性。
- **应用初始化与配置优化**:
- 调整了 [`app/config/config.py`](app/config/config.py) 中日志记录器的获取方式，确保在配置加载早期即可用。
- 在 [`app/core/application.py`](app/core/application.py) 中引入了更明确的数据库连接管理（连接、断开、初始化）逻辑。
- 优化了 [`app/utils/helpers.py`](app/utils/helpers.py) 中项目路径和版本文件路径的定义方式，使其在模块级别初始化。
- **依赖清理**:
- 从 [`requirements.txt`](requirements.txt) 中移除了不必要的注释。
这些更改旨在提升错误日志模块的用户体验和功能性，并优化应用程序的启动和配置管理流程。
