🛡️ Sentinel: [CRITICAL] Prevent use of hardcoded JWT secret in production

This change updates the getJwtSecret function in server/middleware/auth.ts to throw a fatal error if the application is running in production mode and the JWT_SECRET environment variable is not set. This prevents the application from accidentally starting with an insecure, hardcoded default secret.

🚨 Severity: CRITICAL
💡 Vulnerability: Hardcoded JWT secret fallback
🎯 Impact: If exploited, an attacker could forge valid JWT tokens and bypass authentication.
🔧 Fix: Added a check for process.env.NODE_ENV === 'production' and required process.env.JWT_SECRET.
✅ Verification: Verified via manual code review and ensured tests pass in development mode.
