feat(运营报表): AUG26-015 设备激活与套餐续费日报快照、查询趋势与受控导出

- 新增成对迁移 000231 与三张快照表：日级头行、设备粒度激活行、到期事件粒度续费行，以快照日期为唯一键
- 新增每日 03:30（Asia/Shanghai）日报快照生成任务与幂等整日替换，失败重试沿用同一目标日
- 新增六条受控入口：两张报表的汇总、日/月趋势与受控导出，配套查询层只读快照事实
- 新增 operations_activation 与 operations_renewal 两个导出场景，创建期冻结筛选与可见店铺范围、派发期冻结表头、执行期只按冻结值复核资格
- 采购数量口径按系统内未删除设备数实施并在 PRD 标注，附实测差额依据
- 同步证据链 requirement-evidence.json 与入口能力矩阵、ARCHITECTURE 与验证记录
- 归档 change add-operations-reports 并新建主 Spec openspec/specs/operations-report/spec.md
