Summary

• Updates the sample-content MAUI template to use CommunityToolkit.Mvvm 8.4.2.
• Converts template page models from field-backed [ObservableProperty] members to partial observable properties without enabling preview language features.
• Switches the sample-content SQLitePCLRaw dependency from bundle_green to bundle_e_sqlite3 3.0.3 and updates cgmanifest version mapping so generated projects avoid default NuGet audit warnings.

Validation

• dotnet build .\src\Templates\src\Microsoft.Maui.Templates.csproj -p:UpdateCgManifestBeforeBuild=false -p:GenerateCgManifest=false
• Packed templates and generated a dotnet new maui --sample-content true app from an isolated template hive.
• dotnet build <generated app> -f net10.0-windows10.0.19041.0 -p:RestoreIgnoreFailedSources=true completed with 0 warnings and 0 errors, with no generated LangVersion or EnablePreviewFeatures entries.

Mac build validation

The PR description validates on Windows (net10.0-windows). I ran the equivalent validation on macOS to cover the Mac-hosted targets.

What I did: packed the template from this branch → installed into an isolated template hive → generated a dotnet new maui --sample-content true app → built it (host SDK 10.0.100, maui workload).

Mac-hosted target	Result
net10.0-maccatalyst	● Build succeeded — 0 warnings / 0 errors (.app bundle produced)
net10.0-ios	● Build succeeded — 0 warnings / 0 errors

Confirmed on Mac:

• ● Partial [ObservableProperty] properties compile under the default net10 LangVersion — no errors.
• ● The generated .csproj contains no LangVersion / EnablePreviewFeatures entries — i.e. preview language features are not leaked into user projects (the goal of this PR).
• ● CommunityToolkit.Mvvm 8.4.2 + SQLitePCLRaw.bundle_e_sqlite3 3.0.3 restore and build cleanly.
• ● 0 warnings overall → no NuGet audit warnings from the SQLite bundle swap.

Builds cleanly on macOS from a template-generation perspective. ℹ Note: I only exercised the build (no on-device run), and did not test net10.0-android.
