enhance: change from to std::ranges::find_if in Chat::getPrivateChannel

[dudantas]

Description

This pull request 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.

Behaviour

Actual

Iterating over privateChannels using a for loop and checking if the owner's GUID matches the player's GUID manually.

Expected

Using std::ranges::find_if to streamline the search for the private channel, simplifying the code by using a lambda and structured bindings.
