Enable Save button when position flags are modified

[bjpetit]

What changed?

Added .onChange to Position Flag toggles to enable the save button when these values are changed.

Why did it change?

Changing these toggles was not enabling the save button.

How is this tested?

Ran through various iterations of modifying the Position Flag and Advanced Position Flags toggles to verify that the save button was enabled. Also saved configuration changes to ensure that the configuration was being successfully saved.
