feat(templates): add with-cloudflare-website template

[sfsfco]

PR Description

What?

Adds a new template with-cloudflare-website that combines the full-featured Website template with Cloudflare D1 (SQLite) database and R2 object storage infrastructure.

Why?

Currently, Payload offers:

• website template - Full-featured website/blog template with MongoDB
• with-cloudflare-d1 template - Basic Cloudflare D1/R2 setup with minimal collections

Users who want to deploy a production-ready website on Cloudflare's edge network had to manually merge these two templates. This new template provides an out-of-the-box solution for deploying the complete website template on Cloudflare Workers.

Use cases:

• Personal or enterprise-grade websites, blogs, or portfolios on Cloudflare
• Content publishing platforms with edge-first performance
• Global distribution with zero cold starts via Cloudflare's network

How?

Created a new template based on website with the following modifications:

Database & Storage:

• Replaced MongoDB adapter with @payloadcms/db-d1-sqlite (Cloudflare D1)
• Added @payloadcms/storage-r2 plugin for media storage
• Generated initial migration file for all collections (pages, posts, categories, forms, media, users, header, footer)

Cloudflare Configuration:

• Added wrangler.jsonc with D1 and R2 bindings
• Added cloudflare-env.d.ts for TypeScript bindings
• Added open-next.config.ts for OpenNext/Cloudflare integration
• Converted next.config.js to next.config.ts for better TypeScript support

Payload Config Changes:

• Uses sqliteD1Adapter with push: true for development (auto schema sync)
• Uses getCloudflareContext for runtime bindings
• R2 storage configured for media collection

Media Collection:

• Disabled crop and focalPoint features (sharp not available on Workers)

Dynamic Rendering:

• Added export const dynamic = 'force-dynamic' to all pages/layouts
• Removed generateStaticParams from pages (static generation not supported without env vars at build time)

Scripts:

• deploy - Full deployment (database + app)
• deploy:database - Apply migrations to remote D1
• deploy:app - Build and deploy to Cloudflare Workers
• migrate:create / migrate:fresh - Migration utilities
• preview - Local preview with Cloudflare bindings

Documentation:

• Comprehensive README with setup instructions for D1/R2
• Database migration documentation
• Deployment guide
