Implement routing and improve app data management

- Integrated svelte-spa-router for navigation between Home and Preview pages.
- Refactored App.svelte to manage global app data and handle search queries, compact mode, and view mode changes.
- Updated Grid and List components to navigate to the Preview page instead of using modals.
- Created Home.svelte to serve as the main page, utilizing global app data for rendering.
- Enhanced Preview.svelte to fetch logos and display the selected logo based on URL parameters.
- Improved data handling and reactivity across components, ensuring UI updates reflect changes in global state.
- Added logging for better debugging and tracking of state changes.
