Add Monaco-based EditorBlock component

[claudemyburgh]

Created a new React component EditorBlock at resources/js/components/theme/editor-block.tsx that uses @monaco-editor/react.

Key features:

• Mirroring CodeBlock: Uses the same styling, variants, and header structure as the existing CodeBlock component.
• Theme Support: Automatically switches between Monaco's vs-dark and light themes based on the project's useAppearance hook.
• Full-screen Mode: Integrated toggle that uses the Browser Fullscreen API.
• Clipboard Integration: Built-in copy-to-clipboard button using the local useClipboard hook.
• SSR Ready: Implements a mount check to ensure the editor only loads on the client, preventing hydration issues.
• Configurable: Supports common props like language, readOnly, hideLineNumbers, height, and custom Monaco options.

The component is fully typed and includes usage examples in its header.
