系统业务任务插件化迁移：下沉7项非刚需任务并接入平滑迁移

- 系统任务保留刚需三项：登录巡检、消息计数入库、媒体补偿处理；移除新闻/Epic/排行/PDF/秀人维护等业务型系统任务定义\n- 新增 daily_news、epic_free、daily_ranking、sehuatang_push 四个插件，将原系统业务任务改为插件可调度动作\n- 扩展 xiuren_image 插件调度动作，新增秀人下载、绅士R15下载、图片缓存更新三项维护任务\n- 新增系统任务到插件任务的幂等迁移逻辑：按旧 job_key 映射到插件 action，同步 trigger_type/trigger_config/enabled，并通过 payload 标记防止反复覆盖\n- 在 Robot 启动流程中接入迁移执行与重载，并清理已迁移的历史系统任务记录，避免后台双份维护\n- 扩展插件调度数据库操作：支持按 plugin_name + action_key 精确查询，便于迁移与对账
