refactor: 迁移 AnalysisPanel.vue - SVG 图标替代 emoji

完成内容:
- 导入 IconLibrary 组件
- 替换头部标题图标 (analysis)
- 替换标签页图标 (folder, search)
- 替换 AI 提取按钮图标 (sparkles)
- 替换范式卡片操作按钮 (edit, trash)
- 替换分析工具和历史标题图标 (search, edit)
- 优化按钮样式 (flexbox, gap, 居中对齐)
- 标签页按钮支持 flexbox 布局
- 操作按钮添加 aria-label

保留部分:
- iconOptions 数组保留 emoji 并添加 TODO 注释
- 该选择器用于用户自定义范式图标，需后续优化

Emoji 数量: 9 → 0 (除 iconOptions 外)
