test: server 测试共用建库与假引擎,sse-pg 归入串行组

- 新增 apps/server/test/support/{pg,engine}.ts:测试库地址、可用性探测、schema 咨询锁、
  建 schema + 加锁迁移 + 删除、可选去重的假引擎;6 份 harness 改用它(acquisition-organize 与
  file-manager 原先迁移不加锁,并行下有冲突隐患,一并修正)
- sse-pg 起子进程,并行下子进程启动超时,归入 serial
- 修正 b61335e 挪动 / 改名测试后遗留的 import 排序与格式(当时 lint 检查经管道被吞掉退出码)
