Subject: [PATCH 2/2] fix(mobile): resolve iOS build errors by enabling
 buildReactNativeFromSource for Expo SDK 54

Expo SDK 54 switched to precompiled React Native XCFrameworks by default
for faster iOS builds. However, the precompiled frameworks do not expose
legacy bridge headers (RCTBridge, RCTViewManager, RCTSurfaceHostingProxyRootView,
RCTPackagerConnection, RCTDevSettings.isDebuggingRemotely, rootViewFactory)
that some native modules (e.g. expo-dev-client) still reference.

Add expo-build-properties (v1.0.10, the SDK 54-compatible version) and
configure buildReactNativeFromSource: true for iOS. This compiles React
Native from source, making all native headers available to linked modules
and resolving the Xcode compilation errors seen in the EAS production build.

+> **Note:** The mobile app uses `expo-build-properties` with `buildReactNativeFromSource: true` for iOS builds. This is required for Expo SDK 54 (React Native 0.81) compatibility — some native modules still use legacy bridge APIs (`RCTBridge`, `RCTViewManager`, etc.) that are no longer included in the default precompiled XCFrameworks. Building React Native from source makes these headers available, at the cost of slightly longer iOS build times.

 See the [EAS Build documentation](https://docs.expo.dev/build/introduction/) for full setup instructions.
