Dependencies teardown

When using dependency injection in tests, it's important to properly tear down resources after tests complete.

Without proper teardown, the Python event loop might close before resources have a chance to shut down properly, leading to errors like RuntimeError: Event loop is closed.

You can set up automatic teardown using a pytest fixture:

import pytest_asyncio
from typing import AsyncGenerator

from my_project import DIContainer

@pytest_asyncio.fixture(autouse=True)
async def di_container_teardown() -> AsyncGenerator[None]:
    try:
        yield
    finally:
        await DIContainer.tear_down()
