feat: Add authentication and session management with NextAuth.js and Prisma [broken]

- Implemented API session retrieval in `lib/api-auth.ts` to manage user sessions.
- Created authentication options in `lib/auth-options.ts` using NextAuth.js with credentials provider.
- Added migration scripts to create necessary tables for authentication in `migrations/0002_create_auth_tables.sql` and `prisma/migrations/20250601033219_add_nextauth_tables/migration.sql`.
- Configured ESLint with Next.js and TypeScript support in `eslint.config.mjs`.
- Updated Next.js configuration in `next.config.ts` for Cloudflare compatibility.
- Defined Cloudflare Worker configuration in `open-next.config.ts` and `wrangler.jsonc`.
- Enhanced type definitions for authentication in `types/auth.d.ts`.
- Created a Cloudflare Worker entry point in `src/index.ts.backup` to handle API requests and responses.
