- Restyle Fluent controls (buttons, fields, dialogs, ListView) to match the
app's navy dark/light palette and consistent corner radii/sizing
- Fix ContentDialog (Settings, exit-confirm, error) styling by binding
PrimaryButtonStyle/CloseButtonStyle explicitly via new DialogHelper,
since ContentDialog ignores implicit Button styles and forces accent
color onto whichever button is DefaultButton
- Remove MicaBackdrop and theme the title bar directly so it no longer
shows a gray tint mismatched with the app's navy background
- Replace placeholder Assets/*.png (unused VS template art) with the real
AmiReel logo at all required tile/splash/store sizes
- Set explicit default window size (1280x860, matching the old WPF app)
with DPI-aware centering and a minimum size, instead of sizing to content
- Fix drag-and-drop silently failing: InputList_Drop needs a
DragOperationDeferral before the first await or the DataView is torn
down before GetStorageItemsAsync completes
- Add Preview player path setting (was present in WPF, missing in WinUI)
and error handling for preview playback
- Accept all ffmpeg-readable video formats (mp4, mov, mkv, webm, ...) for
file picker and drag-and-drop, not just .avi
- Add exit-confirmation dialog to WinUI, mirroring the WPF app
