Add provider-first property and scope migration helpers

[cwinland]

Summary

• add provider-first property state and property setter capture helpers as a migration path away from simple SetupAllProperties() and setter-interception patterns
• expand typed IServiceProvider and IServiceScope helper coverage, including owned lifetime tracking, provider-backed scope registration, and the corresponding disposal model updates on Mocker
• extend analyzer migration support with FMOQ0021 plus broader FMOQ0013 detection and code fixes for typed provider, scope, and context-sensitive scope-factory migration cases
• add runtime tests, analyzer/code-fix tests, sample coverage, and updated migration/testing docs for the new helper surfaces

Validation

• dotnet test .\FastMoq.Analyzers.Tests\FastMoq.Analyzers.Tests.csproj --no-restore
• dotnet test .\FastMoq.Tests\FastMoq.Tests.csproj --no-restore
