style: auto-format with black + isort + prettier [skip ci-format-check]

YAML bug期间CI不触发，代码重构后测试未同步更新，导致14个单元测试失败。

修复内容：
1. video_processing/url_security.py: ALLOWED_VIDEO_MIME_TYPES已移至packages.domain，
   兼容层导入路径错误导致整个模块加载失败，连锁引发多个测试ImportError
2. test_multi_track_subtitle_concat.py: POSITION_ALIGNMENT已移至packages.domain.subtitle_style
3. test_classification.py: AssetLibraryKind新增IMAGE枚举，测试断言从2改为3
