feat: unify sync functionality with event-driven UI updates

- Refactored navbar sync button to dispatch 'sync-completed' event
- Configs page: removed duplicate 'Импорт с сервера' button, added auto-refresh on sync
- Projects page: wrapped initialization in DOMContentLoaded, added auto-refresh on sync
- Pricelists page: added auto-refresh on sync completion
- Consistent UX: all lists update automatically after 'Синхронизация' button click
- Removed code duplication: importConfigsFromServer() function no longer needed
- Event-driven architecture enables easy extension to other pages
