完善成员画像插件的日/周/月分层提取与已结束日期处理逻辑

- 将成员画像能力进一步收敛到插件内部，强化按群启用、后台异步刷新、后台查看的完整链路
- 新增群维度按日批量提取能力：以群为单位按天处理一次，统一提取当天活跃成员的日级画像摘要
- 日级画像输出扩展为更适合长期累计的结构化信号，补充身份线索、技能信号、家庭线索、阶段线索、价值偏好、群内角色、决策风格等字段
- 优化提示词设计，明确要求优先提取可复用、可累计、可验证的行为线索，减少一次性情绪和短期噪声对长期画像的干扰
- 打通日 -> 周 -> 月 -> 最终画像 的分层汇总链路，让后续月度画像直接消费日/周级结构化摘要，而不是重复回扫长窗口原始消息
- 新增/完善画像融合策略：identity_traits、skill_profile、family_profile、life_stage_profile、value_profile 也纳入长期分数累计，不再仅依赖最近一次结果覆盖旧结果
- 将活跃群、活跃成员、辅助消息样本等口径统一调整为只处理已结束日期，避免当天未完结数据进入画像计算
- 调整日级批处理逻辑，默认只处理昨天及更早日期，确保不会处理当天消息
- 修复重复执行时仍然先调用 AI 再跳过的问题，改为先检查当天候选成员是否已完成生成，全部已存在时直接跳过，减少无效 AI 请求和耗时
- 增加群日批处理、周摘要、月摘要、群刷新进度等日志，方便后台定位当前刷新到哪些群、哪些成员、进度如何
- 丰富后台画像展示字段，支持查看更完整的长期画像维度与摘要统计
- 更新插件配置默认值，收敛为近 60 天启动窗口、每日滚动处理与群级日摘要模式
- 补充 message_storage 读取能力，支持按群按日提取消息，为群日批量画像与后续周期汇总提供底层数据支撑
