Refactor manifest generation to use native -FileList support and update tests to remove invalid manifest checks.

Updated the module manifest generator to rely on New-ModuleManifest’s built‑in -FileList parameter, eliminating the need for post‑processing or custom serialization. Adjusted the associated Pester tests to remove Test-ModuleManifest usage and replace it with Import-PowerShellDataFile, preventing warnings caused by missing module files during scaffolding. All tests now run cleanly with no manifest validation noise.
