feat(全栈): 实现简易模式核心功能

**功能概述**：
实现简易模式(Simple Mode)，为个人用户和小团队提供简化的使用体验，隐藏复杂的分组、订阅、配额等概念。

**后端改动**：
1. 配置系统
   - 新增 run_mode 配置项（standard/simple）
   - 支持环境变量 RUN_MODE
   - 默认值为 standard

2. 数据库初始化
   - 自动创建3个默认分组：anthropic-default、openai-default、gemini-default
   - 默认分组配置：无并发限制、active状态、非独占
   - 幂等性保证：重复启动不会重复创建

3. 账号管理
   - 创建账号时自动绑定对应平台的默认分组
   - 如果未指定分组，自动查找并绑定默认分组

**前端改动**：
1. 状态管理
   - authStore 新增 isSimpleMode 计算属性
   - 从后端API获取并同步运行模式

2. UI隐藏
   - 侧边栏：隐藏分组管理、订阅管理、兑换码菜单
   - 账号管理页面：隐藏分组列
   - 创建/编辑账号对话框：隐藏分组选择器

3. 路由守卫
   - 限制访问分组、订阅、兑换码相关页面
   - 访问受限页面时自动重定向到仪表板

**配置示例**：
```yaml
run_mode: simple

run_mode: standard
```

**影响范围**：
- 后端：配置、数据库迁移、账号服务
- 前端：认证状态、路由、UI组件
- 部署：配置文件示例

**兼容性**：
- 简易模式和标准模式可无缝切换
- 不需要数据迁移
- 现有数据不受影响

+简易模式适合个人开发者或内部团队快速使用，不依赖完整 SaaS 功能。

+- 启用方式：设置环境变量 `RUN_MODE=simple`
+- 功能差异：隐藏 SaaS 相关功能，跳过计费流程
+- 安全注意事项：生产环境需同时设置 `SIMPLE_MODE_CONFIRM=true` 才允许启动
