feat(ai-chat): 新增豆包API + AI模型配置项支持动态切换

- 后端新增豆包（火山引擎Ark）API集成：DoubaoController、ToolDoubaoServiceImpl，
  使用OkHttp3 SSE流式对话，兼容OpenAI Chat Completions格式
- 新增DoubaoConfig配置类，读取doubao.api.*配置
- 在eb_system_config表新增ai_chat_model配置项，支持doubao/coze/gemini三种模型切换
- 新增GET /api/front/doubao/ai-model-config接口供前端读取当前模型配置
- 前端ai-nutritionist.vue的sendToAI按系统配置分发到_sendViaDoubao/_sendViaCoze/_sendViaGemini
- 前端models-api.js新增doubaoChatStream/doubaoChat/getAiModelConfig函数
- 附带豆包API测试脚本和数据库初始化SQL
