Add @ecool/react-native-dlfetch and .npmrc

Configure private registry for the @ecool scope (packages/app/.npmrc) and add @ecool/react-native-dlfetch to packages/app/package.json. Update package-lock.json to include the new scoped package and its transitive dependencies (e.g. @ecool/react-native-sdn, axios, @react-native-async-storage/async-storage, qs, moment, merge-options, etc.) so installs resolve from the configured registry.
