refactor(humanitix): drop importlib boilerplate and os.chdir from tests

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

Removes:
- The importlib.util.spec_from_file_location dance in both test files.
- The process-global os.chdir(_parent) calls (the integration test
  file did not restore cwd, leaving it inside humanitix/ for any
  test file collected after it).
- The legacy tests/context.py shim from the pre-SDK-2.0 testbed.

Matches the simpler pattern used in PR #280 (supadata), PR #289
(google-sheets), and PR #307 (coda).
