Refactor uninstall logic, fixed active filter resetting after uninstalling, and list to gallery switch now jumps to selected title

Added FastGalleryPanel.ScrollToPackage to center the previously selected package in gallery view when switching from list view to gallery view. Refactored uninstall logic to have list and gallery views both use a single uninstall method, and added RefreshGameListAsync to update UI and remember/apply active filters after uninstall.
