Fix tests to match decision service API and add filtering to non-streaming endpoint

- Update test mocks from _get_disliked_ids to _get_user_id_safe
- Fix decision service test method names (clear_decision -> remove_decision, etc.)
- Fix positional vs keyword arg assertion in set_decision test
- Add decision_filter param to non-streaming listing_geojson endpoint
