frontend: remove checkbox input success notification

[ES-Alexander]

Current behaviour

The checkbox input currently generates a success notification popup every time it's changed:

Screen.Recording.2025-01-06.at.5.04.11.pm.mov

Unnecessary notifications contribute to notification fatigue, which means people stop paying attention to the actually important ones.

Expected or desired behaviour

Don't generate a notification for input widgets unless they fail to change the parameter / run the specified action.
