fix: fix "Invalid platform macos" in init integration test

Three fixes for the CI "Test react-native-macos init" job:

1. Simplify apple platform resolution in react-native.config.js to
   use the same pattern as ios/android (resolve from cwd directly).

2. Use glob patterns in package.json files array ("scripts/cocoapods/**"
   instead of "scripts/cocoapods") so yarn pack includes directory
   contents. See facebook#56407.

3. Replace `npm install <local-path>` (creates symlinks) with
   `yarn pack` + `npm install <tarball>` + `chmod +x`. The symlink
   approach caused module instance duplication (setFrameworkDefaults
   targeting wrong @react-native/metro-config instance) and missing
   pre-generated codegen headers. The tarball approach matches what
   users get from npm.
