feat(dashboard): enhance widget availability and initialization

- Updated `getAvailableWidgets` method in `DashboardService` to merge default widget types with database entries, ensuring immediate visibility of new widgets post-deployment.
- Introduced `DASHBOARD_WIDGET_TYPE_DEFAULTS` in `initializeWidgetTypes` for canonical widget types, facilitating API merging when database entries are absent.
- Modified `StatusBar.vue` to utilize a computed property for quick access children, improving menu item handling and visibility based on user context.
- Enhanced `LoggedInView.vue` to dynamically return localized widget labels, improving user experience with accurate translations.
