[DEVOPS] Write Nginx configuration for production deployment

[dev-fatima-24]

Priority: high

Description

There is no Nginx configuration for the production server. Nginx must be configured as a reverse proxy for the NestJS backend and Next.js frontend, with SSL termination, gzip compression, and security headers. This is required for the testnet and mainnet deployments.

Acceptance Criteria

• Nginx proxies /api/* to the NestJS backend on port 3001
• Nginx serves the Next.js frontend on port 3000
• SSL termination configured with Let's Encrypt certificates
• Security headers set: X-Frame-Options, X-Content-Type-Options, HSTS
• Gzip compression enabled for JSON and JavaScript responses
