chore(deps): align packages with Expo SDK 54 (react 19.1.0, expo-clipboard 8.x, patch bumps)

- react was ^19.1.0 and resolved to 19.3.0 while react-dom and the React Native renderer are 19.1.0; pin 19.1.0
- expo-clipboard ^55 is the SDK 55 release; SDK 54 expects ~8.0.8 (npx expo install --check)
- patch bumps for expo, expo-router, expo-constants, expo-font, expo-linking, expo-web-browser
- babel-preset-expo is required by babel.config.js, so declare it
