now that we are allowed to use C++23. we now have the luxury of using `std::views::reverse`. - replace `boost::adaptors::transformed` with `std::views::transform` - remove unused `#include <boost/range/adaptor/reversed.hpp>` this change is part of our ongoing effort to modernize our codebase and reduce external dependencies where possible.
