13.3.24 tweaked onChange logging for state and gcode

A quick turn around release to slightly change the logging to OnChange when MQTT updates happen.

Below is an example of what a print log looks like from the serial terminal.
Steps I physically performed:

• I opened the door
• Click Desktop app to send print to printer
• Closed the door while calibrating extrusion
• Waited for Green light after the bed was lowered
• Opened door (light went WHITE)
• Cleaned build place
• Closed door twice within 6 seconds to jump to idle state and lights are turned off
  (I'm off to bed 2am here)
