插件定时能力扩展：接入天气/群总结/百科问答/成员画像并补齐周月触发器编辑

- 将 weather、message_summary、game_task、member_context 从硬编码 async_job 注册迁移为插件调度能力（get_schedule_actions/run_scheduled_action）\n- 保持原有默认时间与默认启用行为，新增执行统计结果用于后台日志展示\n- 为群总结与天气推送增加目标群范围适配，支持按后台配置选择 all/白名单/单群执行\n- 成员交互摘要支持日/周/月三类动作接入调度中心，兼容指定群与全量群刷新\n- 后台插件调度页面新增 every_week_time 与 every_month_last_day_time 的编辑支持
