now that we are allowed to use C++23. we now have the luxury of using
`std::ranges::transform`.
in this change, we:
- replace `boost::transform` with `std::ranges::transform`
- update affected code to work with `std::ranges::transform`
to reduce the dependency to boost for better maintainability, and
leverage standard library features for better long-term support.
this change is part of our ongoing effort to modernize our codebase
and reduce external dependencies where possible.
