Refactor Site Builder Integration and Update Docker Configuration

- Merged the site builder functionality into the main app, enhancing the SiteBuilderWizard component with new steps and improved UI.
- Updated the Docker Compose configuration by removing the separate site builder service and integrating its functionality into the igny8_sites service.
- Enhanced Vite configuration to support code-splitting for builder routes, optimizing loading times.
- Updated package dependencies to include new libraries for state management and form handling.
