feat: 项目负责人+内部任务群+portal 内部身份领取+群主链接归属

- 迁移 0012：projects.owner_userid / tasks.task_chat_id / claims.owner_partner_id
- lib/task-group-service.ts：懒建 appchat 任务群（首个内部群主领取时创建，成员 diff 补员），播报/卡片文案
- wecom-client 新增 appchat create/update/get/send 封装
- OAuth ticket 增可选 uid（v:1 兼容），内部成员领取按 wecom_userid 解析群主身份
- 外部 OAuth 领取人 upsert 打 partner_type='group_owner'
- portal 链接带 ?owner= 穿透 OAuth 往返，claims 记录归属群主
- 后台任务卡「群主链接」面板：复制链接/推送内部群主/任务群状态
- 催办与超期升级同步播报进任务群
