[FEAT]: NestJS Setup Project and Supabase DB Config

📚 Description:

• The project needs a NestJS backend implementation using TypeORM to connect with our existing Supabase PostgreSQL database. The architecture should follow clean code principles and be optimized for the World App ecosystem.

🎯 Task Objectives:

Set up a new NestJS project with the following initial structure, or if you have a better structure go ahead:

src/
  ├── config/           # App & environment configurations
  │   ├── database.config.ts
  │   └── environment.config.ts
  ├── modules/          # Core modules (will expand later)
  │   └── health/      # Health check module
  ├── common/          # Shared code
  │   └── types/       # Type definitions
  └── main.ts

Implement Supabase connection using TypeORM:

• Configure environment variables
• Set up database connection
• Create initial health check endpoint

✅ Acceptance Criteria:

Project Setup:

• Initialize NestJS project with TypeScript
• Install required dependencies
• Implement folder structure
• Create environment variables template

Database Configuration:

• Successfully connect to Supabase using TypeORM
• Environment variables properly set up
• Basic health check endpoint working
• Connection test successful
