Significantly improve ReactiveUI.Uno test coverage from 5.39% to 16.09% and migrate from Moq to NSubstitute (#266)

* Initial plan

* Initial assessment and plan for increasing ReactiveUI.Uno test coverage

Co-authored-by: glennawatson <[email protected]>

* Significantly improve ReactiveUI.Uno test coverage from 5.39% to 14.86%

Co-authored-by: glennawatson <[email protected]>

* Add comprehensive tests for BooleanToVisibilityHint, ActivationHelper, and expand coverage significantly

Co-authored-by: glennawatson <[email protected]>

* Significantly expand test coverage with comprehensive edge cases and platform tests - 70 total tests

Co-authored-by: glennawatson <[email protected]>

* Replace Moq with NSubstitute and fix build environment

Co-authored-by: glennawatson <[email protected]>

* Changes before error encountered

Co-authored-by: glennawatson <[email protected]>

* Update target frameworks and clean up test code

Added .NET 10 target frameworks to build properties and test projects for future compatibility. Updated Uno.Sdk version in global.json and upgraded ReactiveUI.SourceGenerators in SQLiteStudio sample. Removed redundant copyright/license headers from test files, replaced Assert.Multiple with Assert.EnterMultipleScope for NUnit 4 compatibility, and removed unnecessary System.Private.Uri package reference.

* Skip UI tests in headless environments

Added SetUp methods to test classes to detect and skip tests when no UI context is available, preventing failures in headless environments. This improves test reliability across different CI and local setups.
