Refactor: 大幅清理代码注释并优化配置提示

本次提交主要包含以下更改：

- 代码清理:
  - 移除了 `app/router/` 目录下多个路由文件 ([`config_routes.py`](app/router/config_routes.py:1), [`error_log_routes.py`](app/router/error_log_routes.py:1), [`gemini_routes.py`](app/router/gemini_routes.py:1), [`openai_compatiable_routes.py`](app/router/openai_compatiable_routes.py:1), [`openai_routes.py`](app/router/openai_routes.py:1), [`routes.py`](app/router/routes.py:1), [`scheduler_routes.py`](app/router/scheduler_routes.py:1), [`stats_routes.py`](app/router/stats_routes.py:1), [`version_routes.py`](app/router/version_routes.py:1)) 中的大量解释性注释、TODO 注释和多余的日志标记。
  - 清理了 [`scheduler_routes.py`](app/router/scheduler_routes.py:31) 中被注释掉的认证逻辑。
  - 这些清理旨在提高代码的整洁度和可维护性。

- UI 优化:
  - 在 [`app/templates/config_editor.html`](app/templates/config_editor.html:327) 中，为 Gemini 模型的安全过滤级别设置增加了一条重要的提示信息，建议用户将其设置为 "OFF" 以避免影响输出速度，并强调非必要不应随意改动。
