Pull request overview
Cleans up MAUI .NET 10 build warnings by migrating away from APIs that became obsolete (synchronous DisplayAlert/DisplayActionSheet) and from controls that are deprecated (ListView, ViewCell, TextCell, ImageCell, SwitchCell, SelectedItemChangedEventArgs, MediaPicker.PickPhotoAsync).
Changes:
- Renamed
DisplayAlert→DisplayAlertAsyncandDisplayActionSheet→DisplayActionSheetAsyncacross all samples, the Settings page, the SamplePage, and helpers; some fire‑and‑forget calls were rewritten with_ =. - Replaced
ListView(withViewCell/TextCell/ImageCell/SwitchCellitem templates) withCollectionViewplus equivalentDataTemplates, and updated the corresponding code‑behind handler signatures fromSelectedItemChangedEventArgstoSelectionChangedEventArgs(usinge.CurrentSelection.FirstOrDefault()). - Misc.:
MediaPicker.PickPhotoAsync→PickPhotosAsync().FirstOrDefault(); rewroteChangeSublayerVisibilitysublayers page usingCollectionView+Switch; reworkedSimulatedDataSource.ProcessNextObservationto use a nullable‑bool end‑of‑stream signal.

Looks good! One small regression with the portal maps not scrolling and a couple optional nits
