Improve multi-line text, logo, and version display

- Enhance ImageCreatorAlternate to support multi-line text rendering with correct sizing, spacing, and shadow for each line.
- Only draw logos on non-thumbnail images to match GDI behavior.
- Add a status bar to MainWindow showing the app version at runtime.
- Upgrade MinVer to 7.0.0 and adjust versioning to avoid WPF/XAML assembly identity issues.
- Refactor XAML layout to accommodate the new status bar.
