feat: add image classification feature

Added comprehensive image classification system with AI-based
categorization
1. Implemented classification view showing categorized images in grid
layout
2. Added classification detail view for browsing images within specific
categories
3. Integrated with external DBus classification service for AI-powered
image recognition
4. Added classification progress tracking and status notifications
5. Extended database schema to store classification metadata
6. Added sidebar navigation entry for classification feature
7. Implemented automatic classification of unclassified images on first
access

Log: Added image classification feature with AI-based categorization

Influence:
1. Test classification view displays correctly when service is available
2. Verify classification detail view shows proper images for each
category
3. Test classification progress dialog appears during initial
classification
4. Verify sidebar navigation to classification views works correctly
5. Test classification status messages display properly
6. Verify database properly stores and retrieves classification metadata
7. Test handling when classification service is unavailable

feat: 添加图片分类功能

新增基于AI的图片分类系统
1. 实现分类视图，以网格形式显示分类后的图片
2. 添加分类详情视图，用于浏览特定分类下的图片
3. 集成外部DBus分类服务，提供AI驱动的图片识别能力
4. 添加分类进度跟踪和状态通知
5. 扩展数据库结构以存储分类元数据
6. 在侧边栏添加分类功能导航入口
7. 实现首次访问时自动对未分类图片进行分类

Log: 新增基于AI的图片分类功能

Influence:
1. 测试分类服务可用时分类视图正确显示
2. 验证分类详情视图正确显示各分类下的图片
3. 测试初始分类时进度对话框正常显示
4. 验证侧边栏导航到分类视图功能正常
5. 测试分类状态消息正确显示
6. 验证数据库正确存储和检索分类元数据
7. 测试分类服务不可用时的处理逻辑
