Fix deployment: Use local build by default and remove obsolete version

🔧 Deployment Fixes:
- Change default compose file to docker-compose.deploy-local.yml
- Remove obsolete 'version' attribute from compose files
- Ensures deployment works immediately without GitHub Container Registry

✅ Ready to Deploy:
- Use docker-compose.deploy-local.yml (builds locally)
- No more 'version is obsolete' warnings
- No dependency on GitHub Container Registry access

This makes deployment work out-of-the-box while GHCR image access is resolved.
