ci: re-enable react-native-macos-init integration test without Verdaccio

Replace the Verdaccio-based integration test with a simpler approach
that installs the local react-native-macos package directly via
npm install <path>. This avoids the Verdaccio hang issue (#2344)
while still testing the full init flow end-to-end: project creation,
template application, pod install, and macOS build.
