#179 feat: Improve Package.Latest policy test coverage

 Cover the whitespace-only Package.Latest fallback path in
 GetNovaResolvedProjectPackageSettings and keep the latest-policy tests
 deduplicated by reusing the shared package test support helper.

 - add coverage for whitespace-only Package.Latest values
 - replace the local metadata test builder with shared test support
 - keep latest-policy focused tests and full repo validation green
