chore: upgrade monorepo to Expo SDK 55

[JoeSlain]

Description

Upgraded the Expo stack from SDK 54 to SDK 55 and aligned dependent React/React Native versions across the monorepo to avoid peer/version drift.

What changed

• Upgraded apps/expo to Expo SDK 55 (expo, babel-preset-expo, Expo modules, RN ecosystem packages).
• Upgraded apps/storybook-native to Expo SDK 55 and matching Metro preset.
• Ran workspace version harmonization so shared packages and web/storybook apps use the same React/RN family versions.
• Removed invalid Expo config key newArchEnabled from apps/expo/app.json to satisfy SDK 55 schema.
• Updated lockfile after all dependency changes.

Type of Change

• 🐛 Bug fix (non-breaking change which fixes an issue)
• ✨ New feature (non-breaking change which adds functionality)
• 💥 Breaking change (fix or feature that would cause existing functionality to not work as expected)
• 📝 Documentation update
• 🎨 Style update (formatting, renaming)
• ♻️ Code refactoring
• ✅ Tests update
• 🔧 DevOps / Build config

How Has This Been Tested?

• Manual testing

Commands run

• npx expo@latest install expo@^55.0.0 --fix (in apps/storybook-native)
• yarn check-deps:fix
• yarn check-deps
• npx expo-doctor@latest (in apps/expo) → 17/17 checks passed
• Restarted and validated runtime services:

  • curl -I http://localhost:3000
  • curl -I http://localhost:6006

Additional Notes

• Storybook manager starts and is reachable; in this cloud environment the preview iframe remains spinner/loading (pre-existing behavior observed before this migration as well).
• UI text/icon in the demo page still says “Expo SDK 54”; that is display content, not package version source of truth.
