test(cost-calc): stop 182 global writes leaking out of the cost-calc suites (#37815) 
* test(cost-calc): stop 182 global writes leaking out of the cost-calc suites

Across test_cost_calculator.py and llm_cost_calc/test_llm_cost_calc_utils.py,
58 tests opened by setting LITELLM_LOCAL_MODEL_COST_MAP in os.environ and
replacing litellm.model_cost, and none of them put the env var back. The
second file already had a _local_model_cost_map fixture doing it by hand with
a try/finally, so both idioms sat in the same file.

Keep that fixture, give it monkeypatch, and have every one of those tests ask
for it. The margin and discount tests drop their hand-rolled
copy-then-restore in favour of monkeypatch.setattr, which also puts the
global back when an assertion fails part way through.

Both files also drop a sys.path.insert whose argument resolves outside the
repo, so it was never what made the imports work.

TQ003 1077 -> 1075, TQ004 768 -> 693, TQ005 2836 -> 2731, and the budget
ceilings come down with them.

* fix(test): make the streamed-cost tests load the map they assert against

The local_cost_map fixture set LITELLM_LOCAL_MODEL_COST_MAP but never reloaded
litellm.model_cost, and reading the variable is not what loads the map. So the
three streaming-cost tests billed against whatever map the process happened to
be holding, and their hardcoded prices only held when something else had
already swapped in the checked-in one. This branch stops the cost-calc tests
leaking that map, which left test_main billing at the ambient prices instead.

The fixture now loads the map it names, so the prices these tests assert hold
on their own.

Testing for litellm/

This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.

The point of this is to:

  1. Increase test coverage of litellm/
  2. Make it easy for contributors to add tests for the litellm/ package and easily run tests without needing LLM API keys.

File name conventions
