Fix compatibility with Feather Client

[IHaxU]

Type of change

• [x] Bug fix
• [ ] New feature

Description

This modifies ChatHudMixin to ensure compatibility between Meteor Client and Feather client. Using @Local in mixins targeting the addVisibleMessage method causes crashes when used alongside Feather. This change removes the use of @Local, instead manually reconstructing the necessary variables to maintain the same functionality.
