feat: LLM多阶段交互式Schema生成 + UI布局优化

- AI Service: 多阶段对话模型(理解→澄清→生成→校验→确认)，支持对话历史和当前Schema上下文 - Backend: 适配多阶段AI模型，Gateway/Service/Controller传递history和currentSchema - Frontend: AiDesignerChat组件重写，支持阶段徽章、快速回复、Schema校验展示 - Frontend: 表单/流程设计器布局优化，AI助手和Schema预览作为独立列 - Frontend: 流程设计器元数据和模式选择器合并为一行 - Keycloak: 自定义登录主题(中文化) - 修复CSS媒体查询括号平衡问题
