refactor(sts-like-viewer): simplify scene management and config

- Move configuration to `src/config/index.ts`
- Simplify `App.tsx` by passing scene classes directly to `PhaserScene`
- Update `GameUI` initialization to use string ID for container
- Update documentation to mention `initData` for `ReactiveScene`
- Standardize quote usage and formatting in config files

 ### 1. ReactiveScene / GameHostScene
 Extend `ReactiveScene`(`packages\framework\src\scenes\ReactiveScene.ts`) to use reactive integration features.
-- Access game context for scene navigation
 - Use `this.disposables` for auto-cleanup on shutdown.
+- Use `initData` for context data passed from the `<PhaserScene/>` preact component.
 
 ### 2. Spawner Pattern
 Implement `Spawner<TData, TObj>` for data-driven objects.
