Add new interfaces and dependencies for Civic API

Added several interfaces related to petition signatures and Civic API details in `index.d.ts`. Updated `.env.example` with a default AI model, and `package.json` with new dependencies: `@mdxeditor/editor` and `react-error-boundary`. Enhanced global CSS with dark mode styles for the editor.
