- Introduced a new interface `IThumbnailService` for handling thumbnail-related functionalities.
- Registered `IThumbnailService` with its implementation `ThumbnailService` in the service container.
- Updated `NotificationBuilder` to use an instance of `IThumbnailService` instead of static methods.
- Refactored `ThumbnailService` from a static class to a regular class with instance methods and variables.
- Modified `ImagePreviewControl` to utilize the new `IThumbnailService` instance.
- Completed integration of `IThumbnailService` in the application by registering it in `App.xaml.cs`.

* style: Show favicons as squares

- Changed `hintCrop` in `NotificationBuilder` to `None` for app logo display.
- Added `FaviconSquircle`, `FaviconImage`, and `isFavicon` to `ImagePreviewControl` for favicon handling.
