Refactor to support multi-document plugins in React MUI example

Replaces the loader plugin with the document manager plugin and updates the React MUI example to use document-scoped APIs for all plugin interactions. Adds support for new plugins such as print, capture, and history. Refactors all components (toolbar, sidebars, controls, etc.) to accept a documentId prop and use document-specific plugin APIs, enabling multi-document support and improved modularity.
