Pin SfxCA to DTF 5.0.2 so non-elevated setup can extract custom actions

[nefarius]

Summary

• Build managed custom-action packages with WixToolset.Dtf.CustomAction 5.0.2 so the SFXCA stub extracts to a user-writable temp folder instead of C:\Windows\Installer.
• Fail the setup build if the resolved SfxCA.dll is older than 5.0, which is the WiX 4.0.5+ regression that made double-click install and appwiz.cpl uninstall return 1603.

WiX 4.0.6 stays on PATH for wix.exe. Package IDs in WixDtfPackages are lowercase because WixSharp's PackageDir() matches them case-sensitively against the nuget cache.

Test plan

• Local dotnet build -c Release -p:SetupVersion=3.0.0 with WiX 4.0.6 reports SfxCA.dll: 5.0.2.0
• build/SetupRelease.Tests.ps1 plus LFS, versioned-binary, and custom-action package guards pass
• Double-click the signed setup-v3.0.0-r3 MSI from a non-elevated session and confirm install succeeds
• Uninstall from appwiz.cpl from a non-elevated session and confirm the product is removed
• Verbose log shows SFXCA: Extracting custom action to temporary directory: under a user-writable path, not C:\Windows\Installer

If five is not the major sign
