Fix health check - use curl instead of wget

Issues fixed:
1. Removed duplicate health check from Dockerfile (docker-compose overrides it)
2. Switched from wget to curl (more reliable in alpine)
3. Installed curl in the Docker image
4. Simplified health check command

The health check now properly tests if Nginx is serving content on port 7777.
Container should show as healthy after 40s start period.
