Actions: Fix invocation of autobuild PowerShell script

Pass the quoted script path to PowerShell using `-File`.
This ensures the path is treated as a string rather
than a command, and correctly handles file paths
that contain spaces, unblocking integration tests.

Add logging to autobuild.cmd for easier debugging.
