Apply ultra-concise settings shortcuts to TopMessage and HomeView

- TopMessage: Replace 50+ lines of settings logic with single () call
- HomeView: Replace databaseUtil calls with () and ()
- Remove unused imports (MASTER_SETTINGS_KEY, databaseUtil) from HomeView
- Settings updates now use automatic cache invalidation for performance
- Reduce settings boilerplate by 80-90% with cached shortcuts
