refactor(app-business-reviews): drop importlib boilerplate from tests

With tests/conftest.py putting the integration root on sys.path and
the workspace conftest.py patching Integration.load to find config.json,
test files can now import the integration with a plain
'from app_business_reviews import app_business_reviews'.

Removes the importlib.util.spec_from_file_location dance from both
test files and the now-unused dependencies/ sys.path entry. Also
deletes the legacy tests/context.py shim from the pre-SDK-2.0 testbed.

Matches the simpler pattern used in PRs #280, #289, #306, #307.
