feat(adaptive): 完善自适应 RPM 学习并将 Pool 调度状态与健康分解耦

- orchestration 新增 AdaptiveSuccess 效果，在成功回报路径上根据利用率窗口扩张 learned_rpm_limit
- 429 路径改用 429_observation/adjustment 记录以及基于历史的置信度评估，新增 last_rpm_peak 边界字段
- Pool 调度状态不再因 health_score 低或熔断而降级/拦截，前端同步移除相关按钮与文案兜底
- 新增前端 poolTrace 工具（附测试）承接原 HorizontalRequestTimeline 内的候选合并逻辑
