feat: add BootStatusUIView for loading progress display with text feedback

- Create new BootStatusUIView MonoBehaviour component with StatusText and ProgressSlider fields
- Implement SetStatus() and SetProgress() methods for updating UI elements
- Replace Transform-based ProgressFill in LoadingUIView with Slider component for better UX
- Integrate BootStatusUIView into LoadState with real-time status updates during loading steps
- Display formatted progress text (e.g., 'Loading 50%') alongside slider updates
- Add SceneTemplateSettings.json to ProjectSettings for scene template configuration
