feat(frontend): 全部页面接入后端API并同步全局企业选择

- ai-plus: Class组件→函数组件，接入 listHealthScores + listAgentExecutions API
- ooda: 硬编码→接入 risks/weak-signals/sentinels/tasks API 构建OODA各阶段
- threads: 硬编码→接入 risks/tasks/events API 组合决策线程
- today: 硬编码→接入 risks/weak-signals/synergies/reports API 构建行动项
- compare: 硬编码企业名→使用全局企业列表 + listHealthScores + listRisks API
- innovation/knowledge-graph/portfolio: 加 useCompanyScope 标题显示企业名
- 所有页面标题在单企业选择时显示企业名
- 编译验证通过
