Fix Backend `main.ts` Bootstrap and CORS Configuration

Fix Backend Bootstrap and Architecture Issues

• Name / Title: Fix Backend main.ts Bootstrap and CORS Configuration
• Complexity: Low
• Task Type: Backend / Bug
• Description: The NestJS application currently has critical bugs in its entry file (src/main.ts) that prevent it from compiling and communicating with the frontend. AppModule is used in NestFactory.create() but never imported. Furthermore, Cross-Origin Resource Sharing (CORS) is not enabled, which will block all API requests from the Next.js frontend during local development and in production.
• Technical Requirement: NestJS, TypeScript
• Estimated time to deliver: 1 hour
• Acceptance criteria:
  • src/main.ts compiles successfully without missing import errors.
  • CORS is explicitly enabled in main.ts with appropriate origins configured (or open for local dev).
• MUST DOs:
  • Add import { AppModule } from './app.module'; to main.ts.
  • Add app.enableCors() with credentials support if using cookies for JWT, or standard headers if using Authorization headers.
