test: remove the five test functions a later definition shadows (#37591)

Python binds a name once per scope, so when a module or class defines the same
test twice only the last one exists. The earlier definitions are unreachable:
pytest never collects them, and nothing that references them can fail.

A sweep in August cleared nine of these. Five have appeared since, which is the
argument for a rule rather than another sweep.

Each survivor is the better version, so nothing is lost. The two SQS logger
twins additionally stub `asyncio.create_task`, which the shadowed copies did
not. The cost-calculator duplicate is a two-line stub that also takes a
`model_item` parameter no fixture supplies, so it could not have run even
unshadowed. The two `test_prompt_caching` bodies are both `pass`.

Collecting the four files reports 416 tests before and after.

`tests/proxy_unit_tests/conftest copy.py` goes with them. pytest only loads a
file named exactly `conftest.py`, nothing imports this one, and the space in the
name says what it was.
