fix(m0): 迁移可执行 + 测试全绿(33 条)
跑通迁移与测试后修掉的真问题:

- alembic 0001:asyncpg 走预备语句,一次 execute 只能一条 SQL。
  CREATE FUNCTION / CREATE POLICY / GRANT 全部拆成单语句逐条执行,
  否则报 "cannot insert multiple commands into a prepared statement"。
- 创建工作区:ORM flush 只按 relationship 排序,裸外键不算数,
  member 可能先于 workspace 落地撞 FK。改为先 flush workspace 再插 member。
- datetime.UTC 是 3.11+ 才有的,本机 3.10 直接 ImportError。改用 timezone.utc。
- 幂等中间件:原来会缓存 4xx。校验失败被缓存后,用户改对参数仍拿到同一个 422。
  改为只缓存 <400。
- 发码节流窗口改为可配置 SMS_THROTTLE_SECONDS(测试置 0),
  节流用例自己显式打开,避免"整库关掉节流"导致节流从未被验证。
- 租户隔离用例:pytest.raises(Exception) 改为精确的 ProgrammingError,
  否则任何异常都会让"应用角色不能建表"这条断言假通过。

验收:pytest 33 passed;ruff check / format 通过;真机跑 uvicorn,
/health、/version、登录、建工作区、列表、/auth/me 全通。

"""跨租户隔离 —— 本仓库**最重要的测试**(AGENTS.md 2.5)。
三层验证,任何一层失效都算事故:
1. 接口层:A 租户的令牌打不到 B 租户的资源。
2. 数据层:应用角色连库、绑定 A 的上下文,物理上看不到 B 的行(RLS 生效)。
3. 配置层:RLS 确实 ENABLE,且应用角色不是 superuser / BYPASSRLS(否则 RLS 被跳过)。
