checkpoint: 调度任务存储落 PG——jobstore 归一 default + execute 写回真实触发 + 前端 store 字典更新

- ap_scheduler: 默认分组改 SQLAlchemyJobStore on PG，删 RedisJobStore 与 redis_instance；注释/告警口径同步
- node/service: jobstore 归一 default（兼容存量 sqlalchemy 名）；cron/interval/date 写回 task_node.trigger/trigger_args（前端列表可见真实触发）；run_job_now 用独立临时 id，不再覆盖节点既有排程
- enums: 删 APSCHEDULER_LOCK_KEY（jobstore 落 PG 后死锁）
- sys_dict_data: sys_job_store 字典归一 default，删 sqlalchemy 档
- 前端: 任务表单 store 选项与 default 归一
