refactor: 统一扩展消息机制并优化组件结构

1、统一消息系统：将 background、content 和 popup 的通信方式从原生的 chrome.runtime 迁移至 @webext-core/messaging，修复了消息回调返回 undefined 的问题。
2、优化组件结构：将通用组件从 entrypoints/popup/components 迁移至根目录 components，并使用 MUI 重构了 Navbar。
3、同步更新：调整了录制工具 (useRecorder) 和各页面组件（RecordeReplayPage, TestPage等），以适配新的消息协议和组件路径。
