♻️ refactor(tabbar): optimize tab bar navigation implementation

  - 移除动态导入 Taro，改为直接导入以简化代码
  - 优化导航逻辑，提升页面切换性能

🔧 chore(config): update project configuration
  - babel.config.js 添加 targets 配置，指定 ios: '8' 和 android: '4.1' 兼容性
  - babel.config.js 启用 forceAllTransforms 选项增强兼容性处理
  - project.config.json 关闭 es6 转译功能
  - app.config.ts 添加 tabBar 颜色配置和 usingComponents 字段
