Remove dependency on bevy_log feature

Remove dependency on bevy_log feature. Use tracing directly instead and hide it behind a feature

Start by locating the project's bevy_log dependency and feature configuration, then identify where logging is used and how tracing can be made optional. Done means bevy_log is no longer required, tracing is used directly, and the logging behavior remains controlled by a feature.
