feat(output_view): 导出页面重构 - 长图卡片化展示、缩略图增大、预览优化、纯图片页原图保存

Browse Source 
- output_view.html: 长图改为固定高度卡片(70px)，Blob URL查看，缩略图minmax(280px,1fr)，
  竖图预览优先填充视口高度，下载功能完整保留
- phone-image.js: renderPureImageToCanvas()使用naturalWidth/naturalHeight保持原图分辨率，
  新增长图生成和保存功能
- Post.php: 新增outputView()方法提供导出页面渲染数据
- PhoneImage.php: 图片数据改为DB存储，新增saveLongImage()方法
- phone_image.html: 添加导出页面入口按钮
- 新增数据库迁移: post_output_file表添加image_data字段
