chore: 添加缺失的静态资源文件

添加多个前端界面所需的图片、字体、音频等静态资源文件，包括：
- 管理员后台的图标、背景图、组件图片
- 移动端页面的商品图片、用户中心图片、活动图标
- 第三方库的示例图片和字体文件
- 浏览器兼容性配置文件
- 图标字体文件（eot、ttf、woff、woff2格式）

这些资源是前端界面正常显示所必需的，之前可能因版本控制忽略或遗漏而缺失。

+Usage with FlySystem
+===============
+
+For saving or uploading the generated zip, you can use the
+`Flysystem <https://flysystem.thephpleague.com>`_ package, and its many
+adapters.
+
+For that you will need to provide another stream than the ``php://output``
+default one, and pass it to Flysystem ``putStream`` method.
+
+.. code-block:: php
+
+    // Open Stream only once for read and write since it's a memory stream and
+    // the content is lost when closing the stream / opening another one
+    $tempStream = fopen('php://memory', 'w+');
+
+    // Init Options
+    $zipStreamOptions = new Archive();
+    $zipStreamOptions->setOutputStream($tempStream);
+
+    // Create Zip Archive
+    $zipStream = new ZipStream('test.zip', $zipStreamOptions);
+    $zipStream->addFile('test.txt', 'text');
+    $zipStream->finish();
+
+    // Store File (see Flysystem documentation, and all its framework integration)
+    $adapter = new Local(__DIR__.'/path/to/folder'); // Can be any adapter (AWS, Google, Ftp, etc.)
+    $filesystem = new Filesystem($adapter);
+
+    $filesystem->putStream('test.zip', $tempStream)
+
+    // Close Stream
+    fclose($tempStream);
