Production defaults (``request_min_interval=1.0``, ``request_jitter=0.8``)
would make every mocked request sleep ~1-1.8s and balloon the suite's
runtime. In tests we want the *behaviour* (header stealth, backoff, cap)
without the wall-clock cost, so we pin the throttle env vars to 0. The
defaults themselves are still asserted directly via ``Settings`` field
introspection in ``test_config.py``. The cache is cleared on either side
so the zeroed env is picked up the first time a test reads settings.

"""Factory yielding an ``AsyncClient`` over a seeded in-memory SQLite DB.
Mirrors the override pattern established in ``tests/test_api_customer.py``
(``StaticPool`` + single in-memory connection + ``get_session`` dependency
override) but lets each test supply its own seed coroutine so the read-API
test files don't each re-~40-line the boilerplate.
Usage::
async def test_x(make_client):
async def seed(session):
session.add(Department(dept_id="d1", ...))
await session.commit()
client = await make_client(seed)
r = await client.get("/api/departments")
...
The factory owns the engine + client lifetime: both are torn down
(``aclose`` / ``dispose``) and the dependency override cleared when the
test exits.
