feat(report): 报表四页与打印视图

- 个人绩效明细/部门绩效汇总/业务统计/回款统计四页，路由组「报表统计」order19-22（allowedRoles admin/finance/leader）
- 明细分页页脚全筛选合计；部门汇总成员内联与跨页下钻；业务统计展开回款/台账；回款统计 8 档区间（档位由后端下发）与桶下钻
- 打印视图独立顶层路由（不挂 BasicLayout）：公司页眉走 public 端点、循环翻页取全量（2000 行截断提示）、@media print A4 横版每页表头、签字栏
- AppPagination 只派发 page-change/size-change，四页按事件绑定并补初始加载（@change/v-model 不生效的同类缺陷）
- e2e report_flow.py：四页筛选与导出下载、打印视图 window.print 桩断言
