重构: 跨模块样式DRY收口+审批列表增强+灵感模块优化

- 全局样式收口: page-header/btn/modal/filter-bar/back-link/empty-state
  等通用类从12个视图的scoped重复定义提取到global.css/components.css
- 审批列表增强: 筛选栏(状态/风险/工具搜索)+行展开查看完整参数结果
  +审批耗时显示+刷新spinner+硬编码颜色全部改用CSS变量
- 灵感模块: scoreTier统一评分阈值+score-bar/assessment-badge提取全局
  +statusLabelKey消除重复+i18n状态文案对齐+eval-report--muted统一空态
- Dashboard: df-panel/df-link提取全局(修scoped不渗透)+统计卡可点击跳转
  +活跃项目面板只显示active状态+灵感列表按分数排序+刷新spinner
- 修复: intent.rs tool_type类型对齐(newtype)+ToolCardList补ai-btn定义
  +SkillMention/ImageInput样式不渗透修复(提取全局)
