fix(mobile): make expo-modules-autolinking resolvable from the app

pnpm 11 ignores node-linker=hoisted in .npmrc, so node_modules uses the
isolated layout. Expo evaluates expo's react-native.config.js through the
apps/mobile/node_modules/expo symlink, where require('expo-modules-autolinking')
fails silently; autolinking then guessed the import from the Gradle namespace
(expo.core.ExpoModulesPackage) and the release Java compile failed.
