test: Fix apply_json_filter to handle empty string filters and nested key access edge cases (#7340)
* 🐛 (test_apply_json_filter.py): fix test failures by updating expected return values and handling special cases in apply_json_filter function * [autofix.ci] apply automated fixes * 📝 (test_temp_flow_cleanup.py): comment out test_cleanup_worker_run_with_exception to temporarily disable the test for further investigation * [autofix.ci] apply automated fixes * 🐛 (test_apply_json_filter.py): fix logic to handle special characters and numeric keys in nested paths to ensure accurate comparison of results * [autofix.ci] apply automated fixes * ✨ (test_temp_flow_cleanup.py): add get_settings_service dependency to test_cleanup_worker_run_with_exception test to improve test coverage and handle exceptions gracefully. * ♻️ (test_apply_json_filter.py): remove commented-out code and unused imports to clean up the test file and improve readability --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>
