feat(pool): 引入 pro_first 调度预设、Pool 候选持久化跳过与诊断信息优化

- 新增 pro_first 调度预设（Pro 优先），更新 plus_first 仅针对 Plus 计划，移除 free_team_first
- Pool 内部候选（pool_key_index 不为空）跳过 DB 持久化（available/skipped/unused 均适用）
- LRU 排序新增 catalog_lru_score 回退：runtime 无记录时使用 last_used_at_unix_secs
- 执行路径 miss 诊断消息细化为中文，按 reason 分类输出可读说明
- build_local_request_candidate_status_record 补充 extra_data 和 created_at_unix_ms 字段
- OpenAI CLI 计划构建流程补充候选评估进度跟踪与 terminal reason 设置
- 前端 PoolSchedulingDialog 增加 pro_first 预设展示，修复 LRU 默认预设检测逻辑
