Walkthrough

Two theme modules (bolt and delizia) have their borders_notification() helper function removed. This function previously provided standardized inset values for notification borders. The bolt variant returned Insets::new(48, 6, 6, 6) while the delizia variant returned Insets::new(42, 0, 0, 0). Additionally, the delizia module's import statement was simplified by removing the now-unused Insets type.
