ENTERPRISE: Implement zero-config SSL/TLS with dual HTTP/HTTPS architecture

Major architectural improvements:
- Auto-generate SSL certificates on first startup with OpenSSL
- Dual HTTP (8081) + HTTPS (8443) backend API servers
- Frontend auto-detects protocol and uses appropriate API endpoint
- Fix database ORM initialization race condition with getDb() pattern
- WebSocket authentication with JWT verification during handshake
- Zero-config .env file generation for production deployment
- Docker and nginx configurations for container deployment

Technical fixes:
- Eliminate module initialization race conditions in database access
- Replace direct db imports with safer getDb() function calls
- Automatic HTTPS frontend development server (npm run dev:https)
- SSL certificate generation with termix.crt/termix.key
- Cross-platform environment variable support with cross-env

This enables seamless HTTP→HTTPS upgrade with zero manual configuration.
