Deploy KVH PULSE to my production server at adampowell.pro/pulse

Server: 198.211.114.12 (Debian 10, nginx, Node.js v18.20.8)

CRITICAL SETUP REQUIREMENTS:
1. Install PostgreSQL (not currently installed):
   - apt update && apt install -y postgresql postgresql-contrib
   - Create database: kvh_pulse
   - Create user: kvh_pulse_user with secure password
   - Run schema from database/schema.sql

2. Extract kvh-pulse.zip to /var/www/kvh-pulse/

3. Server setup:
   - Location: /var/www/kvh-pulse/server/
   - Port: 3004 (3001-3003 already in use)
   - Install dependencies: npm install
   - Create .env with PostgreSQL credentials, JWT secrets, CORS_ORIGIN=https://adampowell.pro
   - Create systemd service: kvh-pulse.service (like existing maps.service and atlas.service)
   - Enable and start service

4. Client setup:
   - Location: /var/www/kvh-pulse/client/
   - Install dependencies: npm install
   - Build: npm run build
   - Deploy to: /var/www/adampowell.pro/html/pulse/

5. nginx configuration (add to existing adampowell.pro config):
   - /pulse/ → serve static files from /var/www/adampowell.pro/html/pulse/
   - /pulse/api/ → proxy to http://localhost:3004/api/
   - /pulse/socket.io/ → WebSocket proxy to http://localhost:3004/socket.io/
   - Test and reload: nginx -t && systemctl reload nginx

6. Update client Socket.io path to '/pulse/socket.io/' in main.jsx, rebuild, redeploy

7. Create admin user in database (username: admin, password: admin123)

8. Verify:
   - Service running: systemctl status kvh-pulse
   - Port listening: netstat -tlnp | grep 3004
   - Access: https://adampowell.pro/pulse/
   - Login works: admin/admin123

Follow my existing server patterns (check /etc/systemd/system/atlas.service and nginx config for examples).

Set proper permissions (www-data:www-data), create logs directory, ensure HIPAA security settings.

After deployment, I'll change the admin password and update SYSTEM.md.
