feat(image): 添加图像超分处理功能

- 新增 ImageSRStage 类实现图像超分辨率处理
- 在 AioDeviceController 中启用图像超分和增强的 Stage
- 修改 ImageEnhanceStage 配置检查逻辑，增加空值和占位符检测
- 为图像处理 Pipeline 添加超分 Stage
- 增加 ImageSRStage 的单元测试覆盖各种配置和执行情况
- 实现百度云图像超分 API 的调用和结果处理逻辑

+     * 测试说明：
+     *
+     * 由于 ImageSRStage 依赖外部 API (BceImageSR)，
+     * 以下测试场景需要 Mock 或集成测试环境：
+     *
+     * 1. testExecute_Success_ValidConfig()
+     *    - 模拟成功的图像超分辨率调用
+     *    - 验证超分后文件大小变化
+     *    - 验证 context.updateProcessedFile() 被调用
+     *
+     * 2. testExecute_ApiReturnsNull_ShouldDegrade()
+     *    - 模拟 API 返回 null
+     *    - 验证返回 StageResult.degraded()
+     *
+     * 3. testExecute_ApiReturnsEmptyFile_ShouldDegrade()
+     *    - 模拟 API 返回空文件
+     *    - 验证返回 StageResult.degraded()
+     *
+     * 4. testExecute_ApiThrowsException_ShouldDegrade()
+     *    - 模拟 API 抛出异常
+     *    - 验证返回 StageResult.degraded() 而不是 failed()
+     *
+     * 5. testExecute_SaveFileFails_ShouldDegrade()
+     *    - 模拟文件保存失败
+     *    - 验证返回 StageResult.degraded()
+     *
+     * 这些测试需要使用 Mockito 或类似的 Mock 框架来模拟 BceImageSR 的行为。
+     *
+     * 示例（使用 Mockito）：
+     *
+     * @Test
+     * void testExecute_Success_ValidConfig() {
+     *     // 创建 Mock 的 BceImageSR
+     *     BceImageSR mockSR = mock(BceImageSR.class);
+     *
+     *     // 创建 Mock 的 MultipartFile
+     *     MultipartFile mockEnhancedImage = mock(MultipartFile.class);
+     *     when(mockEnhancedImage.isEmpty()).thenReturn(false);
+     *     when(mockEnhancedImage.getBytes()).thenReturn(new byte[]{1, 2, 3, 4, 5, 6, 7, 8});
+     *
+     *     // 配置 Mock 行为
+     *     when(mockSR.enhance(anyString())).thenReturn(mockEnhancedImage);
+     *
+     *     // 测试逻辑...
+     * }
+     */
