ESM module import compatibility

[jfeingold]

When attempting to launch the project following the documentation, "import Phaser" was not working due to ESM/CommonJS module import mismatches.

Simple update of these import statements to use "import * as Phaser" so that the code runs.

Note

Low Risk
Low risk import-only change; main risk is if some tooling relied on the default Phaser export, but usage remains unchanged via the Phaser namespace.

Overview
Fixes Phaser ESM/CommonJS interop issues by switching import Phaser from 'phaser' to import * as Phaser from 'phaser' in the React app (App.jsx), shared EventBus, and game bootstrap (main.js), keeping all existing Phaser.* usages intact.
