* Resolve PR comments

* Remove toggle for channels so any channel listed will be logged

* Move Only log channels listed below checkbox to just above table

* Fix formatting

* Re-order changelog

* ChannelLog constructor: Copy & move instead of const ref & copy

* ChannelLog::createEmpty: Curly brace initialize instead of repeating
name

* ChannelLog toString & createEmpty: nodiscard

* Use COUNT paradigm in model column

* Remove ChanneLoggingModel source file comments

* Use Column::Channel in getRowFromItem

* Rename `getItemFromRow` parameter and mark it as unused

* Curly brace initialize ChannelLog

* private & friend class the model
