fix: downgrade to Expo SDK 55 for Expo Go compatibility

SDK 56 requires a newer Expo Go version not yet available on the
Play Store. Downgrade to SDK 55 which is compatible with the
currently published Expo Go app.

- expo: ~55.0.26, react-native: 0.83.6, react: 19.2.0
- All expo-* packages aligned to SDK 55
- Added metro.config.js extending expo/metro-config
- Removed newArchEnabled from app.json (not in SDK 55 schema)
- Added expo-dev-client as fallback for development builds
- expo-doctor passes 19/19 checks
- TypeScript clean, Convex functions deploy successfully

+This project uses [Convex](https://convex.dev) as its backend.
+
+When working on Convex code, **always read
+`convex/_generated/ai/guidelines.md` first** for important guidelines on
+how to correctly use Convex APIs and patterns. The file contains rules that
+override what you may have learned about Convex from training data.
+
+Convex agent skills for common tasks can be installed by running
+`npx convex ai-files install`.
