feat: 租户级系统提示词 + 模块权限树

1. 系统提示词按租户配置：
   - 去掉所有硬编码的'奇瑞汽车'品牌名
   - realtime_chat 的 _build_chat_prompt 按 tenant_id 动态获取提示词
   - _generate_response 和 _generate_response_stream 都传递 tenant_id
   - 默认提示词为通用客服助手（不含品牌名）
   - 租户编辑弹窗新增系统提示词配置区

2. 模块权限树：
   - Tenant config 新增 modules 字段（14个模块的开关）
   - GET /api/tenants/my-modules 返回当前用户所属租户的模块权限
   - 前端 applyModulePermissions() 初始化时隐藏无权限的侧边栏标签
   - 租户编辑弹窗新增模块权限 checkbox 配置区
   - 默认全部模块开启，取消勾选即隐藏

3. 其他清理：
   - llm_client.py 通用提示词去掉品牌名
   - react_agent.py SYSTEM_PROMPT 去掉'车辆'限定
