Subject: [PATCH] Refactor group selection logic to store all search results

- Replaced `selected_indices` with `selected` attribute on candidate objects.
- Updated frontend `createGroup` to include all candidates.
- Updated backend `solver.py` to filter by `selected` attribute.
- Updated tests to match new data structure.
