新建 backend/tests/fixtures/postgres.py，提供两层 fixture：
- postgres_container (session 级)：用 PostgresContainer 起 postgres:16-alpine
- postgres_url (function 级)：每 test 一个 ephemeral DB，teardown 时
pg_terminate_backend 清掉残连后 DROP DATABASE
为什么 per-DB 而不是 per-schema：asyncpg + SQLAlchemy 不通过 URL 传 search_path，
per-DB 一次 ~50ms 开销可接受，让 test 代码不感知 schema。
Docker 不可用时 fixture 自动 pytest.skip 而非 error，dev 环境无 Docker
仍能跑其余 3086 个测试。
注册 pytest mark `postgres`、把 tests/ 加 sys.path 让 pytest_plugins
按 `fixtures.postgres` 路径解析（不加 tests/__init__.py 避免干扰
现有 pytest 发现行为）。
