fix: 修复browser_installer.py语法错误，同步服务器代码

Browse Source 
- 修复browser_installer.py顶部错误的import语句
- 移除browser_installer.py中未正确实现的_cleanup_zombie_processes方法
- 恢复playwright_automation.py中的SIGKILL（服务器版本）
- 同步database.py和email_service.py的最新代码

注意：内存占用从50MB增加到142MB是正常的，因为：
1. 4个浏览器Worker线程（按需模式）占用基础内存
2. 新增的清理代码和SIGCHLD处理器占用少量内存
3. 当前内存使用在正常范围内
