Welcome Screen + Prefs QA (#1362)

Set the default editor theme to automatic in defaults.txt. Added a slight delay in file watching to reduce CPU usage. Enhanced the WelcomeSurvey UI with a border for better visual feedback. Refactored zoom preference handling in Interface.kt to use lambdas for up-to-date values.
