Improve security of the backend

[Joshna907]

Input Validation & Sanitization: Ensure all user inputs are validated and sanitized to prevent attacks like SQL injection and XSS.

Secure Environment Variables: Move sensitive information (API keys, database credentials) to environment variables and add a .env.example file.

Add Secure Headers: Implement secure headers (using helmet) to prevent clickjacking, XSS, and content sniffing.

JWT Security: Ensure JWT tokens use secure algorithms (e.g., RS256), set expiration, and add refresh tokens.
