Pull request overview

This PR modernizes several multi-array sorting sites by replacing the removed custom bubble_sort_by helper with std::ranges::sort over std::views::zip, keeping related containers permuted consistently while using standard library algorithms.

Changes:

• Replaced bubble_sort_by calls with std::ranges::sort(std::views::zip(...), ...) in multiple call sites to sort multiple correlated sequences together.
• Removed the unused bubble_sort_by implementation and related concepts from src/core/util/sorting.h.
• Updated includes/formatting where needed to support the new ranges-based sorting.
