Fixes a critical issue where MediaPicker would incorrectly dismiss the entire modal page instead of just the camera UI when used from within a modal context on iOS.

Problem

When calling MediaPicker.CapturePhotoAsync() or MediaPicker.CaptureVideoAsync() from within a modal page on iOS, canceling the camera UI would unexpectedly dismiss the entire modal page, not just the camera interface. This happened because the dismissal logic was calling DismissViewControllerAsync on the wrong view controller.

Solution

Changed the dismissal logic in MediaPicker.ios.cs from:

await vc.DismissViewControllerAsync(true);

to:

await picker.DismissViewControllerAsync(true);

This ensures that only the camera picker is dismissed, not the parent modal page that presented it.

Testing

Added comprehensive UI tests (Issue31075) that verify:

Modal pages remain open after MediaPicker interactions
Both photo and video picker scenarios are covered
Tests are disabled on Windows platform where MediaPicker behaves differently

Platform: iOS
Target Branch: net10.0

@copilot please remove all formatting changes from this PR and just keep functional changes

Done! I've removed all formatting changes from the PR and kept only the functional changes. The commit f7cf8f2 reverts all the code style/formatting changes while preserving:

The functional fix in MediaPicker.ios.cs (changed dismissal from vc.DismissViewControllerAsync to picker.DismissViewControllerAsync)
The test files for Issue31075 validation

The PR now contains only the minimal changes needed to fix the modal dismissal issue.

@copilot please fix these build errors

Fixed the build errors by replacing the non-existent UITestCategories (MediaPicker and Modal) with existing categories (Navigation and Page). The test now compiles successfully on all platforms. Commit: 660230e

@copilot I have verified this fix is correct, can you target the net10.0 branch and apply the fix there? Also the UI test can be disabled for Windows

@copilot I have verified this fix is correct, can you target the net10.0 branch and apply the fix there? Also the UI test can be disabled for Windows

Done! I've successfully applied the MediaPicker modal fix to the net10.0 branch and disabled the UI test for Windows as requested. The changes include:

Applied the same MediaPicker fix to net10.0: Changed await vc.DismissViewControllerAsync(true) to await picker.DismissViewControllerAsync(true) in MediaPicker.ios.cs
Created comprehensive test coverage: Added Issue31075 test files including host app pages and UI tests
Disabled Windows tests: Wrapped the entire test class in #if !WINDOWS directive to exclude Windows platform execution

The fix is now available on the copilot/fix-31075-net10 branch targeting the net10.0 codebase. Commit: 2f8c7a9a
