Complete Expo SDK 56 upgrade

- Upgrade expo, expo-router, expo-dev-client, expo-crypto, expo-localization,
  expo-location, expo-navigation-bar, expo-notifications, expo-secure-store,
  expo-status-bar, expo-system-ui, expo-web-browser to SDK 56 versions
- Upgrade react-native 0.83.4 → 0.85.3
- Upgrade TypeScript 5.9 → 6.0.3 (required by SDK 56)
- Add react-native-worklets (required peer dep for react-native-reanimated)
- Remove expo-dev-menu as a direct dependency (transitive, managed by Expo)
- Move splash config from top-level ExpoConfig to expo-splash-screen plugin
  (ExpoConfig.splash was removed in SDK 56 types)
- Add expo-localization and expo-splash-screen to plugins array
- Fix metro.config.js watchFolders to merge with Expo defaults instead of
  overwriting them (fixes expo-doctor Metro config check)
- Add types: ["jest"] to tsconfig.json (required for jest globals in TS 6)
- Exclude @sentry/react-native from Expo version validation (bundledNativeModules
  has a stale entry; Sentry 8.x officially supports Expo 51+ and RN 0.73+)
