Open-next Cloudflare / Docker / Setup (#248)

* Add Cloudflare generator with Wrangler and OpenNext support

This update introduces a new Cloudflare generator to streamline configuration and deployment via Wrangler and OpenNext. It registers the necessary templates, modifies project files, and adds Cloudflare-specific scripts and dependencies to the package.json. Additionally, .hbs files are updated in .prettierignore for formatting consistency.

* Add GitHub username prompt and improve setup scripts

Introduce a prompt for GitHub username to personalize project setup. Enhance the setup scripts by adding PNPM verification, configuring `upstream` remote, and removing the `origin` remote. Adjust health check and error handling for better reliability.

* Add Dockerfile generator to turbo generators

Introduced a new generator to create Dockerfile configurations for standalone Next.js applications. This includes modifying `next.config.mjs` for standalone output, updating dependencies in `package.json`, and adding a Dockerfile template. The generator is now registered in the turbo setup.

* Add console-based logger implementation. This is required for edge environments such as Cloudflare.

* Remove deprecated Supabase client utilities

The `server-actions-client`, `route-handler-client`, and `server-component-client` utilities have been removed in favor of `getSupabaseServerClient`. This simplifies and consolidates the API, ensuring consistency across server-side usage. Version bumped to 2.9.0 to reflect breaking changes.
