feat: initialize project with event order form

This commit establishes the initial structure of the Nuxt application, centered around a new event order form.

Key changes include:
- Setting up the main app layout with a header, footer, and color mode support using @nuxt/ui.
- Creating a multi-part event order form on the index page.
- Introducing a `useEventOrder` composable to manage form state and validation with Zod.
- Adding modular form components under `app/components/eventOrder`.
- Including project configuration files for pnpm, VSCode, and global CSS.
