Remove obsolete Coolify deployment files

- Removed deploy-to-coolify.example.sh (replaced by deploy-to-apps.example.sh)
- Removed COOLIFY_SETUP.md (replaced by DEPLOYMENT_GUIDE.md)
- Updated .gitignore to remove deploy-to-coolify.sh reference
- Updated README troubleshooting to use SAAC API instead of direct Coolify API

All users now deploy via the SAAC API at apps.startanaicompany.com rather than directly to Coolify.
