feat: 添加SMTP邮件通知功能

新增功能：
- 支持SMTP邮件通知平台，可通过邮件接收系统通知
- 支持配置SMTP服务器、端口、用户名、密码、发件人和收件人
- 支持TLS/SSL加密连接
- 提供美观的HTML邮件模板和纯文本备用格式

代码优化：
- 重构邮件格式化逻辑，提取buildNotificationDetails减少重复代码
- 优化前端表单验证逻辑，提取validatePlatformForm统一验证
- 清理UI中的冗余提示信息和配置项

UI改进：
- 移除SMTP配置说明文字
- 移除超时设置和忽略TLS证书验证选项
- 简化测试成功提示消息
- SMTP平台显示收件人邮箱而非URL
