The isolate_litellm_state conftest fixture saved/restored litellm.callbacks
but never cleared it before each test, unlike the other callback lists. It
also didn't handle litellm.model_fallbacks. Leaked callbacks and fallback
config caused mocked tests to route through Router/fallback paths, hitting
real APIs with mock keys.

Many tests across the llms group (sap, compactifai, vercel_ai_gateway, mistral,
zai, heroku) set litellm.disable_aiohttp_transport = True without restoring it.
When these tests run before test_ssl_context_transport or test_session_reuse_chain
in the same xdist worker, _create_async_transport() returns None (because aiohttp
is disabled AND force_ipv4 is False), causing both tests to fail with
'assert None is not None'.
Fix: extend isolate_litellm_state in conftest.py to also save and restore
disable_aiohttp_transport and force_ipv4, following the same pattern already
used for callbacks.

Critical fix for Greptile feedback: The setup_and_teardown fixture was
missing the autouse=True parameter, causing the module reload logic to
never execute. This would result in test pollution as callbacks would
chain across modules.
Changes:
- Add autouse=True to setup_and_teardown fixture in conftest.py
- Add autouse=True to setup_and_teardown fixture in conftest_improved.py
Note: conftest_improved.py is intentionally kept as a reference
implementation showing the recommended improvements. It demonstrates
better patterns for test isolation that can be adopted later.

- Replace asyncio.get_event_loop_policy() with asyncio.new_event_loop()
- Use asyncio.set_event_loop() to set the event loop
- Fixes deprecation warning in Python 3.16
- Updated both conftest.py and conftest_improved.py
