enhance: change from to std::ranges::find_if in Chat::getPrivateChann…

…el (opentibiabr#2996)

This refactors the iteration and conditional logic used to
find a specific `PrivateChatChannel` in `privateChannels` to use
`std::ranges::find_if`. The updated version of the code improves
readability by reducing boilerplate, leveraging structured bindings and
modern C++ features.
