test: Fix integration test isolation

[vdusek]

• Fix integration test isolation to prevent random directories in project root.

Problem

Running integration tests created random-named directories (e.g., 41SJFVD7V6, KEIN9WBF32) in the project root instead of using temporary directories.

Root cause

The main tests/integration/conftest.py was missing the prepare_test_env fixture that sets APIFY_LOCAL_STORAGE_DIR to a pytest-managed temporary directory. Without this, Crawlee's default behavior creates randomly-named directories in the current working directory.

Changes

1. Added prepare_test_env fixture to tests/integration/conftest.py

   • Sets APIFY_LOCAL_STORAGE_DIR to tmp_path
   • Resets Actor and service locator global state between tests
   • Runs automatically via _isolate_test_environment (autouse=True)

2. Removed duplicate tests/integration/apify_api/conftest.py

   • Contained identical fixtures now provided by parent conftest
   • Tests inherit fixtures through pytest's conftest hierarchy

Testing

After this fix, all storage directories are created under pytest's temporary directory and automatically cleaned up after test runs.
