Subject: [PATCH] fix: preserve base_url and parameters in referenced testcases

- Add preservation of original testcase''s base_url and parameters when referenced
- Fix issue where referenced testcases would inherit the parent''s base_url instead of their own
- Fix issue where referenced testcases would lose their parameters
- Maintain backward compatibility by only preserving explicitly set values
- Add test to verify the fix works correctly

Resolves #1780
