feat: 后台增加对话配置+工具配置管理

新增对话配置页面:
- 配置普通对话使用的LLM、可用工具
- 历史记录数、Temperature、系统提示词
- 支持多配置、设为默认

搜索配置改为工具配置:
- 工具类型: search/calculator/image/code/weather/custom
- 搜索作为工具之一管理
- 支持添加多种工具
- 工具配置: ID、名称、类型、提供商、API、Key、额外配置

API新增:
- /api/admin/chat - 对话配置CRUD
- /api/admin/tools - 工具配置CRUD
- /api/config 返回 tools 和 chat_config
