Update React to 19.0.0 or Move to Peer Dependency

[roni-castro-shipt]

Currently, React is listed as a dependency (see package.json) rather than a peer dependency. This can lead to issues such as multiple versions of React being installed in the project. For example, if the app uses React 19, it may result in two different React versions being bundled—one from the app and another from react-native-style-tachyons package.
