feat(cds-mobile): widen react-native peer dependency to support 0.83.x

## Summary

`@coinbase/cds-mobile` currently pins `react-native: ~0.81.5` across all v9 releases (9.0.0–9.4.1). Apps on React Native 0.83.x cannot install CDS without `--legacy-peer-deps`, which is a hard blocker for projects following strict peer resolution.

## Current peer requirement

## Requested change

Widen the peer range to include 0.83.x, e.g.:

or upgrade the baseline to target Expo SDK 55/56 when that's available.

## Context

React Native 0.83 ships with React 19.2 and has no user-facing breaking changes from 0.81. The React peer conflict that existed in CDS 8 is resolved in v9 — the remaining blocker is solely the `react-native` peer range.

Other peer deps that would also need revisiting for a 0.83 baseline: `react-native-reanimated`, `react-native-gesture-handler`, `react-native-safe-area-context`.

## Impact

Any project on RN 0.83 / Expo SDK 55+ that wants to adopt CDS is blocked at install. This prevents adoption for teams keeping up with the RN release cadence.

Start by locating the @coinbase/cds-mobile v9 package metadata and its react-native peer dependency, then inspect the peer ranges for reanimated, gesture-handler, and safe-area-context. Done means React Native 0.83.x or Expo SDK 55+ installs CDS without --legacy-peer-deps while the existing peer requirements remain compatible.
