Settings: option to skip stop local node screen

[selsta]

Closes #3732

Needs good testing as I had issues with settings resetting after running this patch.

It seems that it's not possible to save any value to persistentSettings after wallet "close event" is called.

That is the reason why I decided to implement a dropdown on Settings > Node page in #2898, and that's why I wasn't able to implement a "Don't ask me again" checkbox on the dialog.

Please check #2898.

I don't change any value after the "close event" is called is called.

I basically did the same, just on the Settings -> Interface page where it fits better IMO.

The new checkbox in settings -> interface highlighted below:

works as intended, ive tried combinations of setting / un-setting / closing / opening wallet and all changes persisted / acted correctly.

The only improvement i can think of would be to perhaps add something along the lines of ' Disable this prompt in settings -> interface ' here: (a new string to avoid translation nightmares? if this is causing headaches let me know)

Line 2090 in b26f38d

confirmationDialog.text = qsTr("Do you want to stop local node or keep it running in the background?") + translationManager.emptyString;

i prefer this PR over #2898 , simpler / elegant
LGTM
