[Xcode 26.4] Release build emits reorder-init-list and symbol-less object warnings

[Malakof]

Summary

A clean iOS Release simulator build with react-native-safe-area-context 5.8.0 emits two -Wreorder-init-list diagnostics per architecture from RNCSafeAreaProviderComponentView.mm. Under Xcode 26.4.1, libtool also warns that RNCSafeAreaViewState.o has no symbols when its implementation is compiled out for the selected platform/configuration.

Environment

• react-native-safe-area-context: 5.8.0
• React Native: 0.86.0
• Expo: 57.0.4
• Xcode: 26.4.1
• SDK: iOS 26.2 simulator
• configuration: Release, new architecture

Diagnostics

RNCSafeAreaProviderComponentView.mm:110:27: warning: ISO C++ requires field designators to be specified in declaration order; field left will be initialized after field bottom [-Wreorder-init-list]
RNCSafeAreaProviderComponentView.mm:111:26: warning: ISO C++ requires field designators to be specified in declaration order; field bottom will be initialized after field right [-Wreorder-init-list]
libtool: warning: RNCSafeAreaViewState.o has no symbols

Source-level fixes verified locally

1. Initialize EdgeInsets in declaration order: top, right, bottom, left.
2. Ensure RNCSafeAreaViewState.cpp emits a real external-linkage symbol even when platform guards compile out the implementation.

These changes remove the diagnostics without warning flags, suppression, or log filtering. I can prepare a focused patch if useful.
